+Tracing in U-Boot
+=================
+
+U-Boot supports a simple tracing feature which allows a record of excecution
+to be collected and sent to a host machine for analysis. At present the
+main use for this is to profile boot time.
+
+
+Overview
+--------
+
+The trace feature uses GCC's instrument-functions feature to trace all
+function entry/exit points. These are then recorded in a memory buffer.
+The memory buffer can be saved to the host over a network link using
+tftpput or by writing to an attached memory device such as MMC.
+
+On the host, the file is first converted with a tool called 'proftool',
+which extracts useful information from it. The resulting trace output
+resembles that emitted by Linux's ftrace feature, so can be visually
+displayed by pytimechart.
+
+
+Quick-start using Sandbox
+-------------------------
+
+Sandbox is a build of U-Boot that can run under Linux so it is a convenient
+way of trying out tracing before you use it on your actual board. To do
+this, follow these steps:
+
+Add the following to include/configs/sandbox.h (if not already there)
+
+#define CONFIG_TRACE
+#define CONFIG_CMD_TRACE
+#define CONFIG_TRACE_BUFFER_SIZE (16 << 20)
+#define CONFIG_TRACE_EARLY_SIZE (8 << 20)
+#define CONFIG_TRACE_EARLY
+#define CONFIG_TRACE_EARLY_ADDR 0x00100000
+
+Build sandbox U-Boot with tracing enabled:
+
+$ make FTRACE=1 O=sandbox sandbox_config
+$ make FTRACE=1 O=sandbox
+
+Run sandbox, wait for a bit of trace information to appear, and then capture
+a trace:
+
+$ ./sandbox/u-boot

+=>sb save host 0 trace 0 ${profoffset}
+11405888 bytes written in 10 ms (1.1 GiB/s)
+=>reset
+
+
+Then run proftool to convert the trace information to ftrace format.
+
+$ ./sandbox/tools/proftool -m sandbox/System.map -p trace dump-ftrace >trace.txt
+
+Finally run pytimechart to display it:
+
+$ pytimechart trace.txt
+
+Using this tool you can zoom and pan across the trace, with the function
+calls on the left and little marks representing the start and end of each
+function.
+
+
+CONFIG Options
+--------------
+
+- CONFIG_TRACE
+ Enables the trace feature in U-Boot.
+
+- CONFIG_CMD_TRACE
+ Enables the trace command.
+
+- CONFIG_TRACE_BUFFER_SIZE
+ Size of trace buffer to allocate for U-Boot. This buffer is
+ used after relocation, as a place to put function tracing
+ information. The address of the buffer is determined by
+ the relocation code.
+
+- CONFIG_TRACE_EARLY
+ Define this to start tracing early, before relocation.
+
+- CONFIG_TRACE_EARLY_SIZE
+ Size of 'early' trace buffer. Before U-Boot has relocated
+ it doesn't have a proper trace buffer. On many boards
+ you can define an area of memory to use for the trace
+ buffer until the 'real' trace buffer is available after
+ relocation. The contents of this buffer are then copied to
+ the real buffer.
+
+- CONFIG_TRACE_EARLY_ADDR
+ Address of early trace buffer
+
+
+Building U-Boot with Tracing Enabled
+------------------------------------
+
+Pass 'FTRACE=1' to the U-Boot Makefile to actually instrument the code.
+This is kept as a separate option so that it is easy to enable/disable
+instrumenting from the command line instead of having to change board
+config files.
+
+
+Collecting Trace Data
+---------------------
+
+When you run U-Boot on your board it will collect trace data up to the
+limit of the trace buffer size you have specified. Once that is exhausted
+no more data will be collected.
+
+Collecting trace data has an affect on execution time/performance. You
+will notice this particularly with trvial functions - the overhead of
+recording their execution may even exceed their normal execution time.
+In practice this doesn't matter much so long as you are aware of the
+effect. Once you have done your optimisations, turn off tracing before
+doing end-to-end timing.
+
+The best time to start tracing is right at the beginning of U-Boot. The
+best time to stop tracing is right at the end. In practice it is hard
+to achieve these ideals.
+
+This implementation enables tracing early in board_init_f(). This means
+that it captures most of the board init process, missing only the
+early architecture-specific init. However, it also misses the entire
+SPL stage if there is one.
+
+U-Boot typically ends with a 'bootm' command which loads and runs an
+OS. There is useful trace data in the execution of that bootm
+command. Therefore this implementation provides a way to collect trace
+data after bootm has finished processing, but just before it jumps to
+the OS. In practical terms, U-Boot runs the 'fakegocmd' environment
+variable at this point. This variable should have a short script which
+collects the trace data and writes it somewhere.
+
+Trace data collection relies on a microsecond timer, accesed through
+timer_get_us(). So the first think you should do is make sure that
+this produces sensible results for your board. Suitable sources for
+this timer include high resolution timers, PWMs or profile timers if
+available. Most modern SOCs have a suitable timer for this. Make sure
+that you mark this timer (and anything it calls) with
+__attribute__((no_instrument_function)) so that the trace library can
+use it without causing an infinite loop.
+
+
+Commands
+--------
+
+The trace command has variable sub-commands:
+
+- stats
+ Display tracing statistics
+
+- pause
+ Pause tracing
+
+- resume
+ Resume tracing
+
+- funclist [<addr> <size>]
+ Dump a list of functions into the buffer
+
+- calls [<addr> <size>]
+ Dump function call trace into buffer
+
+If the address and size are not given, these are obtained from environment
+variables (see below). In any case the environment variables are updated
+after the command runs.
+
+
+Environment Variables
+---------------------
+
+The following are used:
+
+- profbase
+ Base address of trace output buffer
+
+- profoffset
+ Offset of first unwritten byte in trace output buffer
+
+- profsize
+ Size of trace output buffer
+
+All of these are set by the 'trace calls' command.
+
+These variables keep track of the amount of data written to the trace
+output buffer by the 'trace' command. The trace commands which write data
+to the output buffer can use these to specify the buffer to write to, and
+update profoffset each time. This allows successive commands to append data
+to the same buffer, for example:
+
+ trace funclist 10000 e00000
+ trace calls
+
+(the latter command appends more data to the buffer).
+
+
+- fakegocmd
+ Specifies commands to run just before booting the OS. This
+ is a useful time to write the trace data to the host for
+ processing.
+
+
+Writing Out Trace Data
+----------------------
+
+Once the trace data is in an output buffer in memory there are various ways
+to transmit it to the host. Notably you can use tftput to send the data
+over a network link:
+
+fakegocmd=trace pause; usb start; set autoload n; bootp;
+ trace calls 10000000 1000000;
+ tftpput ${profbase} ${profoffset} 192.168.1.4:/tftpboot/calls
+
+This starts up USB (to talk to an attached USB Ethernet dongle), writes
+a trace log to address 10000000 and sends it to a host machine using
+TFTP. After this, U-Boot will boot the OS normally, albeit a little
+later.
+
+
+Converting Trace Output Data
+----------------------------
+
+The trace output data is kept in a binary format which is not documented
+here. To convert it into something useful, you can use proftool.
+
+This tool must be given the U-Boot map file and the trace data received
+from running that U-Boot. It produces a text output file.
+
+Options
+ -m <map_file>
+ Specify U-Boot map file
+
+ -p <trace_file>
+ Specifiy profile/trace file
+
+Commands:
+
+- dump-ftrace
+ Write a text dump of the file in Linux ftrace format to stdout
+
+
+Viewing the Trace Data
+----------------------
+
+You can use pytimechart for this (sudo apt-get pytimechart might work on
+your Debian-style machine, and use your favourite search engine to obtain
+documentation). It expects the file to have a .txt extension. The program
+has terse user interface but is very convenient for viewing U-Boot
+profile information.
+
+
+Workflow Suggestions
+--------------------
+
+The following suggestions may be helpful if you are trying to reduce boot
+time:
+
+1. Enable CONFIG_BOOTSTAGE and CONFIG_BOOTSTAGE_REPORT. This should get
+you are helpful overall snapshot of the boot time.
+
+2. Build U-Boot with tracing and run it. Note the difference in boot time
+(it is common for tracing to add 10% to the time)
+
+3. Collect the trace information as descibed above. Use this to find where
+all the time is being spent.
+
+4. Take a look at that code and see if you can optimise it. Perhaps it is
+possible to speed up the initialisation of a device, or remove an unused
+feature.
+
+5. Rebuild, run and collect again. Compare your results.
+
+6. Keep going until you run out of steam, or your boot is fast enough.
+
+
+Configuring Trace
+-----------------
+
+There are a few parameters in the code that you may want to consider.
+There is a function call depth limit (set to 15 by default). When the
+stack depth goes above this then no tracing information is recorded.
+The maximum depth reached is recorded and displayed by the 'trace stats'
+command.
+
+
+Future Work
+-----------
+
+Tracing could be a little tidier in some areas, for example providing
+run-time configuration options for trace.
+
+Some other features that might be useful:
+
+- Trace filter to select which functions are recorded
+- Sample-based profiling using a timer interrupt
+- Better control over trace depth
+- Compression of trace information

+The CROS_EC (Matrix Keyboard Protocol) allows communcation with a secondary
+micro used for keyboard, and possible other features.
+
+The CROS_EC keyboard uses this protocol to receive key scans and produce input
+in U-Boot.
+
+Required properties :
+- compatible : "google,cros-ec-keyb"
+- google,key-rows : Number of key rows
+- google,key-columns : Number of key columns
+
+Optional properties, in addition to those specified by the shared
+matrix-keyboard bindings:
+
+- linux,fn-keymap: a second keymap, same specification as the
+ matrix-keyboard-controller spec but to be used when the KEY_FN modifier
+ key is pressed.
+- google,repeat-delay-ms : delay in milliseconds before repeat starts
+- google,repeat-rate-ms : delay between each subsequent key press
+- google,ghost-filter : enable ghost filtering for this device
+
+Example, taken from daisy:
+
+cros-ec-keyb {
+ compatible = "google,cros-ec-keyb";
+ google,key-rows = <8>;
+ google,key-columns = <13>;
+ google,ghost-filter;
+ google,repeat-delay-ms = <240>;
+ google,repeat-rate-ms = <30>;
+ /*
+ * Keymap entries take the form of 0xRRCCKKKK where
+ * RR=Row CC=Column KKKK=Key Code
+ * The values below are for a US keyboard layout and
+ * are taken from the Linux driver. Note that the
+ * 102ND key is not used for US keyboards.

+Chrome OS CROS_EC Binding
+======================
+
+The device tree node which describes the operation of the CROS_EC interface
+is as follows:
+
+Required properties :
+- compatible = "google,cros-ec"
+
+Optional properties :
+- spi-max-frequency : Sets the maximum frequency (in Hz) for SPI bus
+ operation
+- i2c-max-frequency : Sets the maximum frequency (in Hz) for I2C bus
+ operation
+- ec-interrupt : Selects the EC interrupt, defined as a GPIO according
+ to the platform
+- optimise-flash-write : Boolean property - if present then flash blocks
+ containing all 0xff will not be written, since we assume that the EC
+ uses that pattern for erased blocks
+
+The CROS_EC node should appear as a subnode of the interrupt that connects it
+to the EC (e.g. i2c, spi, lpc). The reg property (as usual) will indicate
+the unit address on that bus.
+
+
+Example
+=======
+
+ spi@131b0000 {

+U-Boot FIT Signature Verification
+=================================
+
+Introduction
+------------
+FIT supports hashing of images so that these hashes can be checked on
+loading. This protects against corruption of the image. However it does not
+prevent the substitution of one image for another.
+
+The signature feature allows the hash to be signed with a private key such
+that it can be verified using a public key later. Provided that the private
+key is kept secret and the public key is stored in a non-volatile place,
+any image can be verified in this way.
+
+See verified-boot.txt for more general information on verified boot.
+
+
+Concepts
+--------
+Some familiarity with public key cryptography is assumed in this section.
+
+The procedure for signing is as follows:
+
+ - hash an image in the FIT
+ - sign the hash with a private key to produce a signature
+ - store the resulting signature in the FIT
+
+The procedure for verification is:
+
+ - read the FIT
+ - obtain the public key
+ - extract the signature from the FIT
+ - hash the image from the FIT
+ - verify (with the public key) that the extracted signature matches the
+ hash
+
+The signing is generally performed by mkimage, as part of making a firmware
+image for the device. The verification is normally done in U-Boot on the
+device.
+
+
+Algorithms
+----------
+In principle any suitable algorithm can be used to sign and verify a hash.
+At present only one class of algorithms is supported: SHA1 hashing with RSA.
+This works by hashing the image to produce a 20-byte hash.
+
+While it is acceptable to bring in large cryptographic libraries such as
+openssl on the host side (e.g. mkimage), it is not desirable for U-Boot.
+For the run-time verification side, it is important to keep code and data
+size as small as possible.
+
+For this reason the RSA image verification uses pre-processed public keys
+which can be used with a very small amount of code - just some extraction
+of data from the FDT and exponentiation mod n. Code size impact is a little
+under 5KB on Tegra Seaboard, for example.
+
+It is relatively straightforward to add new algorithms if required. If
+another RSA variant is needed, then it can be added to the table in
+image-sig.c. If another algorithm is needed (such as DSA) then it can be
+placed alongside rsa.c, and its functions added to the table in image-sig.c
+also.
+
+
+Creating an RSA key and certificate
+-----------------------------------
+To create a new public key, size 2048 bits:
+
+$ openssl genrsa -F4 -out keys/dev.key 2048
+
+To create a certificate for this:
+
+$ openssl req -batch -new -x509 -key keys/dev.key -out keys/dev.crt
+
+If you like you can look at the public key also:
+
+$ openssl rsa -in keys/dev.key -pubout
+
+
+Device Tree Bindings
+--------------------
+The following properties are required in the FIT's signature node(s) to
+allow thes signer to operate. These should be added to the .its file.
+Signature nodes sit at the same level as hash nodes and are called
+signature@1, signature@2, etc.
+
+- algo: Algorithm name (e.g. "sha1,rs2048")
+
+- key-name-hint: Name of key to use for signing. The keys will normally be in
+a single directory (parameter -k to mkimage). For a given key <name>, its
+private key is stored in <name>.key and the certificate is stored in
+<name>.crt.
+
+When the image is signed, the following properties are added (mandatory):
+
+- value: The signature data (e.g. 256 bytes for 2048-bit RSA)
+
+When the image is signed, the following properties are optional:
+
+- timestamp: Time when image was signed (standard Unix time_t format)
+
+- signer-name: Name of the signer (e.g. "mkimage")
+
+- signer-version: Version string of the signer (e.g. "2013.01")
+
+- comment: Additional information about the signer or image
+
+For config bindings (see Signed Configurations below), the following
+additional properties are optional:
+
+- sign-images: A list of images to sign, each being a property of the conf
+node that contains then. The default is "kernel,fdt" which means that these
+two images will be looked up in the config and signed if present.
+
+For config bindings, these properties are added by the signer:
+
+- hashed-nodes: A list of nodes which were hashed by the signer. Each is
+ a string - the full path to node. A typical value might be:
+
+ hashed-nodes = "/", "/configurations/conf@1", "/images/kernel@1",
+ "/images/kernel@1/hash@1", "/images/fdt@1",
+ "/images/fdt@1/hash@1";
+
+- hashed-strings: The start and size of the string region of the FIT that
+ was hashed
+
+Example: See sign-images.its for an example image tree source file and
+sign-configs.its for config signing.
+
+
+Public Key Storage
+------------------
+In order to verify an image that has been signed with a public key we need to
+have a trusted public key. This cannot be stored in the signed image, since
+it would be easy to alter. For this implementation we choose to store the
+public key in U-Boot's control FDT (using CONFIG_OF_CONTROL).
+
+Public keys should be stored as sub-nodes in a /signature node. Required
+properties are:
+
+- algo: Algorithm name (e.g. "sha1,rs2048")
+
+Optional properties are:
+
+- key-name-hint: Name of key used for signing. This is only a hint since it
+is possible for the name to be changed. Verification can proceed by checking
+all available signing keys until one matches.
+
+- required: If present this indicates that the key must be verified for the
+image / configuration to be considered valid. Only required keys are
+normally verified by the FIT image booting algorithm. Valid values are
+"image" to force verification of all images, and "conf" to force verfication
+of the selected configuration (which then relies on hashes in the images to
+verify those).
+
+Each signing algorithm has its own additional properties.
+
+For RSA the following are mandatory:
+
+- rsa,num-bits: Number of key bits (e.g. 2048)
+- rsa,modulus: Modulus (N) as a big-endian multi-word integer
+- rsa,r-squared: (2^num-bits)^2 as a big-endian multi-word integer
+- rsa,n0-inverse: -1 / modulus[0] mod 2^32
+
+
+Signed Configurations
+---------------------
+While signing images is useful, it does not provide complete protection
+against several types of attack. For example, it it possible to create a
+FIT with the same signed images, but with the configuration changed such
+that a different one is selected (mix and match attack). It is also possible
+to substitute a signed image from an older FIT version into a newer FIT
+(roll-back attack).
+
+As an example, consider this FIT:
+
+/ {
+ images {
+ kernel@1 {
+ data = <data for kernel1>
+ signature@1 {
+ algo = "sha1,rsa2048";
+ value = <...kernel signature 1...>
+ };
+ };
+ kernel@2 {
+ data = <data for kernel2>
+ signature@1 {
+ algo = "sha1,rsa2048";
+ value = <...kernel signature 2...>
+ };
+ };
+ fdt@1 {
+ data = <data for fdt1>;
+ signature@1 {
+ algo = "sha1,rsa2048";
+ vaue = <...fdt signature 1...>
+ };
+ };
+ fdt@2 {
+ data = <data for fdt2>;
+ signature@1 {
+ algo = "sha1,rsa2048";
+ vaue = <...fdt signature 2...>
+ };
+ };
+ };
+ configurations {
+ default = "conf@1";
+ conf@1 {
+ kernel = "kernel@1";
+ fdt = "fdt@1";
+ };
+ conf@1 {
+ kernel = "kernel@2";
+ fdt = "fdt@2";
+ };
+ };
+};
+
+Since both kernels are signed it is easy for an attacker to add a new
+configuration 3 with kernel 1 and fdt 2:
+
+ configurations {
+ default = "conf@1";
+ conf@1 {
+ kernel = "kernel@1";
+ fdt = "fdt@1";
+ };
+ conf@1 {
+ kernel = "kernel@2";
+ fdt = "fdt@2";
+ };
+ conf@3 {
+ kernel = "kernel@1";
+ fdt = "fdt@2";
+ };
+ };
+
+With signed images, nothing protects against this. Whether it gains an
+advantage for the attacker is debatable, but it is not secure.
+
+To solved this problem, we support signed configurations. In this case it
+is the configurations that are signed, not the image. Each image has its
+own hash, and we include the hash in the configuration signature.
+
+So the above example is adjusted to look like this:
+
+/ {
+ images {
+ kernel@1 {
+ data = <data for kernel1>
+ hash@1 {
+ algo = "sha1";
+ value = <...kernel hash 1...>
+ };
+ };
+ kernel@2 {
+ data = <data for kernel2>
+ hash@1 {
+ algo = "sha1";
+ value = <...kernel hash 2...>
+ };
+ };
+ fdt@1 {
+ data = <data for fdt1>;
+ hash@1 {
+ algo = "sha1";
+ value = <...fdt hash 1...>
+ };
+ };
+ fdt@2 {
+ data = <data for fdt2>;
+ hash@1 {
+ algo = "sha1";
+ value = <...fdt hash 2...>
+ };
+ };
+ };
+ configurations {
+ default = "conf@1";
+ conf@1 {
+ kernel = "kernel@1";
+ fdt = "fdt@1";
+ signature@1 {
+ algo = "sha1,rsa2048";
+ value = <...conf 1 signature...>;
+ };
+ };
+ conf@2 {
+ kernel = "kernel@2";
+ fdt = "fdt@2";
+ signature@1 {
+ algo = "sha1,rsa2048";
+ value = <...conf 1 signature...>;
+ };
+ };
+ };
+};
+
+
+You can see that we have added hashes for all images (since they are no
+longer signed), and a signature to each configuration. In the above example,
+mkimage will sign configurations/conf@1, the kernel and fdt that are
+pointed to by the configuration (/images/kernel@1, /images/kernel@1/hash@1,
+/images/fdt@1, /images/fdt@1/hash@1) and the root structure of the image
+(so that it isn't possible to add or remove root nodes). The signature is
+written into /configurations/conf@1/signature@1/value. It can easily be
+verified later even if the FIT has been signed with other keys in the
+meantime.
+
+
+Verification
+------------
+FITs are verified when loaded. After the configuration is selected a list
+of required images is produced. If there are 'required' public keys, then
+each image must be verified against those keys. This means that every image
+that might be used by the target needs to be signed with 'required' keys.
+
+This happens automatically as part of a bootm command when FITs are used.
+
+
+Enabling FIT Verification
+-------------------------
+In addition to the options to enable FIT itself, the following CONFIGs must
+be enabled:
+
+CONFIG_FIT_SIGNATURE - enable signing and verfication in FITs
+CONFIG_RSA - enable RSA algorithm for signing
+
+
+Testing
+-------
+An easy way to test signing and verfication is to use the test script
+provided in test/vboot/vboot_test.sh. This uses sandbox (a special version
+of U-Boot which runs under Linux) to show the operation of a 'bootm'
+command loading and verifying images.
+
+A sample run is show below:
+
+$ make O=sandbox sandbox_config
+$ make O=sandbox
+$ O=sandbox ./test/vboot/vboot_test.sh
+Simple Verified Boot Test

+
+Future Work
+-----------
+- Roll-back protection using a TPM is done using the tpm command. This can
+be scripted, but we might consider a default way of doing this, built into
+bootm.
+
+
+Possible Future Work
+--------------------
+- Add support for other RSA/SHA variants, such as rsa4096,sha512.
+- Other algorithms besides RSA
+- More sandbox tests for failure modes
+- Passwords for keys/certificates
+- Perhaps implement OAEP
+- Enhance bootm to permit scripted signature verification (so that a script
+can verify an image but not actually boot it)

+U-Boot Verified Boot
+====================
+
+Introduction
+------------
+Verified boot here means the verification of all software loaded into a
+machine during the boot process to ensure that it is authorised and correct
+for that machine.
+
+Verified boot extends from the moment of system reset to as far as you wish
+into the boot process. An example might be loading U-Boot from read-only
+memory, then loading a signed kernel, then using the kernel's dm-verity
+driver to mount a signed root filesystem.
+
+A key point is that it is possible to field-upgrade the software on machines
+which use verified boot. Since the machine will only run software that has
+been correctly signed, it is safe to read software from an updatable medium.
+It is also possible to add a secondary signed firmware image, in read-write
+memory, so that firmware can easily be upgraded in a secure manner.
+
+
+Signing
+-------
+Verified boot uses cryptographic algorithms to 'sign' software images.
+Images are signed using a private key known only to the signer, but can
+be verified using a public key. As its name suggests the public key can be
+made available without risk to the verification process. The private and
+public keys are mathematically related. For more information on how this
+works look up "public key cryptography" and "RSA" (a particular algorithm).
+
+The signing and verification process looks something like this:
+
+
+ Signing Verification
+ ======= ============
+
+ +--------------+ *
+ | RSA key pair | * +---------------+
+ | .key .crt | * | Public key in |
+ +--------------+ +------> public key ----->| trusted place |
+ | | * +---------------+
+ | | * |
+ v | * v
+ +---------+ | * +--------------+
+ | |----------+ * | |
+ | signer | * | U-Boot |
+ | |----------+ * | signature |--> yes/no
+ +---------+ | * | verification |
+ ^ | * | |
+ | | * +--------------+
+ | | * ^
+ +----------+ | * |
+ | Software | +----> signed image -------------+
+ | image | *
+ +----------+ *
+
+
+The signature algorithm relies only on the public key to do its work. Using
+this key it checks the signature that it finds in the image. If it verifies
+then we know that the image is OK.
+
+The public key from the signer allows us to verify and therefore trust
+software from updatable memory.
+
+It is critical that the public key be secure and cannot be tampered with.
+It can be stored in read-only memory, or perhaps protected by other on-chip
+crypto provided by some modern SOCs. If the public key can ben changed, then
+the verification is worthless.
+
+
+Chaining Images
+---------------
+The above method works for a signer providing images to a run-time U-Boot.
+It is also possible to extend this scheme to a second level, like this:
+
+1. Master private key is used by the signer to sign a first-stage image.
+2. Master public key is placed in read-only memory.
+2. Secondary private key is created and used to sign second-stage images.
+3. Secondary public key is placed in first stage images
+4. We use the master public key to verify the first-stage image. We then
+use the secondary public key in the first-stage image to verify the second-
+state image.
+5. This chaining process can go on indefinitely. It is recommended to use a
+different key at each stage, so that a compromise in one place will not
+affect the whole change.
+
+
+Flattened Image Tree (FIT)
+--------------------------
+The FIT format is alreay widely used in U-Boot. It is a flattened device
+tree (FDT) in a particular format, with images contained within. FITs
+include hashes to verify images, so it is relatively straightforward to
+add signatures as well.
+
+The public key can be stored in U-Boot's CONFIG_OF_CONTROL device tree in
+a standard place. Then when a FIT it loaded it can be verified using that
+public key. Multiple keys and multiple signatures are supported.
+
+See signature.txt for more information.

+ * fdt_find_regions() - find regions in device tree
+ *
+ * Given a list of nodes to include and properties to exclude, find
+ * the regions of the device tree which describe those included parts.
+ *
+ * The intent is to get a list of regions which will be invariant provided
+ * those parts are invariant. For example, if you request a list of regions
+ * for all nodes but exclude the property "data", then you will get the
+ * same region contents regardless of any change to "data" properties.
+ *
+ * This function can be used to produce a byte-stream to send to a hashing
+ * function to verify that critical parts of the FDT have not changed.
+ *
+ * Nodes which are given in 'inc' are included in the region list, as
+ * are the names of the immediate subnodes nodes (but not the properties
+ * or subnodes of those subnodes).
+ *
+ * For eaxample "/" means to include the root node, all root properties
+ * and the FDT_BEGIN_NODE and FDT_END_NODE of all subnodes of /. The latter
+ * ensures that we capture the names of the subnodes. In a hashing situation
+ * it prevents the root node from changing at all Any change to non-excluded
+ * properties, names of subnodes or number of subnodes would be detected.
+ *
+ * When used with FITs this provides the ability to hash and sign parts of
+ * the FIT based on different configurations in the FIT. Then it is
+ * impossible to change anything about that configuration (include images
+ * attached to the configuration), but it may be possible to add new
+ * configurations, new images or new signatures within the existing
+ * framework.
+ *
+ * Adding new properties to a device tree may result in the string table
+ * being extended (if the new property names are different from those
+ * already added). This function can optionally include a region for
+ * the string table so that this can be part of the hash too.
+ *
+ * The device tree header is not included in the list.
+ *
+ * @fdt: Device tree to check
+ * @inc: List of node paths to included
+ * @inc_count: Number of node paths in list
+ * @exc_prop: List of properties names to exclude
+ * @exc_prop_count: Number of properties in exclude list
+ * @region: Returns list of regions
+ * @max_region: Maximum length of region list
+ * @path: Pointer to a temporary string for the function to use for
+ * building path names
+ * @path_len: Length of path, must be large enough to hold the longest
+ * path in the tree
+ * @add_string_tab: 1 to add a region for the string table
+ * @return number of regions in list. If this is >max_regions then the
+ * region array was exhausted. You should increase max_regions and try
+ * the call again.
