+Generic Distro Configuration Concept
+====================================
+
+Linux distributions are faced with supporting a variety of boot mechanisms,
+environments or bootloaders (PC BIOS, EFI, U-Boot, Barebox, ...). This makes
+life complicated. Worse, bootloaders such as U-Boot have a configurable set
+of features, and each board chooses to enable a different set of features.
+Hence, distros typically need to have board-specific knowledge in order to
+set up a bootable system.
+
+This document defines a common set of U-Boot features that are required for
+a distro to support the board in a generic fashion. Any board wishing to
+allow distros to install and boot in an out-of-the-box fashion should enable
+all these features. Linux distros can then create a single set of boot
+support/install logic that targets these features. This will allow distros
+to install on many boards without the need for board-specific logic.
+
+In fact, some of these features can be implemented by any bootloader, thus
+decoupling distro install/boot logic from any knowledge of the bootloader.
+
+This model assumes that boards will load boot configuration files from a
+regular storage mechanism (eMMC, SD card, USB Disk, SATA disk, etc.) with
+a standard partitioning scheme (MBR, GPT). Boards that cannnot support this
+storage model are outside the scope of this document, and may still need
+board-specific installer/boot-configuration support in a distro.
+
+To some extent, this model assumes that a board has a separate boot flash
+that contains U-Boot, and that the user has somehow installed U-Boot to this
+flash before running the distro installer. Even on boards that do not conform
+to this aspect of the model, the extent of the board-specific support in the
+distro installer logic would be to install a board-specific U-Boot package to
+the boot partition partition during installation. This distro-supplied U-Boot
+can still implement the same features as on any other board, and hence the
+distro's boot configuration file generation logic can still be board-agnostic.
+
+Locating Bootable Disks
+-----------------------
+
+Typical desktop/server PCs search all (or a user-defined subset of) attached
+storage devices for a bootable partition, then load the bootloader or boot
+configuration files from there. A U-Boot board port that enables the features
+mentioned in this document will search for boot configuration files in the
+same way.
+
+Thus, distros do not need to manipulate any kind of bootloader-specific
+configuration data to indicate which storage device the system should boot
+from.
+
+Distros simply need to install the boot configuration files (see next
+section) in an ext2/3/4 or FAT partition, mark the partition bootable (via
+the MBR bootable flag, or GPT legacy_bios_bootable attribute), and U-Boot (or
+any other bootloader) will find those boot files and execute them. This is
+conceptually identical to creating a grub2 configuration file on a desktop
+PC.
+
+Note that in the absense of any partition that is explicitly marked bootable,
+U-Boot falls back to searching the first valid partition of a disk for boot
+configuration files. Other bootloaders are recommended to do the same, since
+I believe that partition table bootable flags aren't so commonly used outside
+the realm of x86 PCs.
+
+U-Boot can also search for boot configuration files from a TFTP server.
+
+Boot Configuration Files
+------------------------
+
+The standard format for boot configuration files is that of extlinux.conf, as
+handled by U-Boot's "syslinux" (disk) or "pxe boot" (network). This is roughly
+as specified at:
+
+http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
+
+... with the exceptions that the BootLoaderSpec document:
+
+* Prescribes a separate configuration per boot menu option, whereas U-Boot
+ lumps all options into a single extlinux.conf file. Hence, U-Boot searches
+ for /extlinux/extlinux.conf then /boot/extlinux/extlinux.conf on disk, or
+ pxelinux.cfg/default over the network.
+
+* Does not document the fdtdir option, which automatically selects the DTB to
+ pass to the kernel.
+
+One example extlinux.conf generated by the Fedora installer is:
+

+------------------------------------------------------------
+
+U-Boot Implementation
+=====================
+
+Enabling the distro options
+---------------------------
+
+In your board configuration file, include the following:
+
+------------------------------------------------------------
+#ifndef CONFIG_SPL_BUILD
+#include <config_distro_defaults.h>
+#include <config_distro_bootcmd.h>
+#endif
+------------------------------------------------------------
+
+The first of those headers primarily enables a core set of U-Boot features,
+such as support for MBR and GPT partitions, ext* and FAT filesystems, booting
+raw zImage and initrd (rather than FIT- or uImage-wrapped files), etc. Network
+boot support is also enabled here, which is useful in order to boot distro
+installers given that distros do not commonly distribute bootable install
+media for non-PC targets at present.
+
+Finally, a few options that are mostly relevant only when using U-Boot-
+specific boot.scr scripts are enabled. This enables distros to generate a
+U-Boot-specific boot.scr script rather than extlinux.conf as the boot
+configuration file. While doing so is fully supported, and
+<config_distro_defaults.h> exposes enough parameterization to boot.scr to
+allow for board-agnostic boot.scr content, this document recommends that
+distros generate extlinux.conf rather than boot.scr. extlinux.conf is intended
+to work across multiple bootloaders, whereas boot.scr will only work with
+U-Boot. TODO: document the contract between U-Boot and boot.scr re: which
+environment variables a generic boot.scr may rely upon.
+
+The second of those headers sets up the default environment so that $bootcmd
+is defined in a way that searches attached disks for boot configuration files,
+and executes them if found.
+
+Required Environment Variables
+------------------------------
+
+The U-Boot "syslinux" and "pxe boot" commands require a number of environment
+variables be set. Default values for these variables are often hard-coded into
+CONFIG_EXTRA_ENV_SETTINGS in the board's U-Boot configuration file, so that
+the user doesn't have to configure them.
+
+fdt_addr:
+
+ Mandatory for any system that provides the DTB in HW (e.g. ROM) and wishes
+ to pass that DTB to Linux, rather than loading a DTB from the boot
+ filesystem. Prohibited for any other system.
+
+ If specified a DTB to boot the system must be available at the given
+ address.
+
+fdt_addr_r:
+
+ Mandatory. The location in RAM where the DTB will be loaded or copied to when
+ processing the fdtdir/devicetreedir or fdt/devicetree options in
+ extlinux.conf.
+
+ This is mandatory even when fdt_addr is provided, since extlinux.conf must
+ always be able to provide a DTB which overrides any copy provided by the HW.
+
+ A size of 1MB for the FDT/DTB seems reasonable.
+
+ramdisk_addr_r:
+
+ Mandatory. The location in RAM where the initial ramdisk will be loaded to
+ when processing the initrd option in extlinux.conf.
+
+ It is recommended that this location be highest in RAM out of fdt_addr_,
+ kernel_addr_r, and ramdisk_addr_r, so that the RAM disk can vary in size
+ and use any available RAM.
+
+kernel_addr_r:
+
+ Mandatory. The location in RAM where the kernel will be loaded to when
+ processing the kernel option in the extlinux.conf.
+
+ The kernel should be located within the first 128M of RAM in order for the
+ kernel CONFIG_AUTO_ZRELADDR option to work, which is likely enabled on any
+ distro kernel. Since the kernel will decompress itself to 0x8000 after the
+ start of RAM, kernel_addr_rshould not overlap that area, or the kernel will

+
+Boot Target Configuration
+-------------------------
+
+<config_distro_bootcmd.h> defines $bootcmd and many helper command variables
+that automatically search attached disks for boot configuration files and
+execute them. Boards must provide configure <config_distro_bootcmd.h> so that
+it supports the correct set of possible boot device types. To provide this
+configuration, simply define macro BOOT_TARGET_DEVICES prior to including
+<config_distro_bootcmd.h>. For example:
+
+------------------------------------------------------------
+#ifndef CONFIG_SPL_BUILD
+#define BOOT_TARGET_DEVICES(func) \
+ func(MMC, mmc, 1) \
+ func(MMC, mmc, 0) \
+ func(USB, usb, 0) \
+ func(PXE, pxe, na) \
+ func(DHCP, dhcp, na)
+#include <config_distro_bootcmd.h>
+#endif
+------------------------------------------------------------
+
+Each entry in the macro defines a single boot device (e.g. a specific eMMC
+device or SD card) or type of boot device (e.g. USB disk). The parameters to
+the func macro (passed in by the internal implementation of the header) are:
+
+- Upper-case disk type (MMC, SATA, SCSI, IDE, USB, DHCP, PXE).
+- Lower-case disk type (same options as above).
+- ID of the specific disk (MMC only) or ignored for other types.
+
+User Configuration
+==================
+
+Once the user has installed U-Boot, it is expected that the environment will
+be reset to the default values in order to enable $bootcmd and friends, as set
+up by <config_distro_bootcmd.h>. After this, various environment variables may
+be altered to influence the boot process:
+
+boot_targets:
+
+ The list of boot locations searched.
+
+ Example: mmc0, mmc1, usb, pxe
+
+ Entries may be removed or re-ordered in this list to affect the boot order.
+
+boot_prefixes:
+
+ For disk-based booting, the list of directories within a partition that are
+ searched for boot configuration files (extlinux.conf, boot.scr).
+
+ Example: / /boot/
+
+ Entries may be removed or re-ordered in this list to affect the set of
+ directories which are searched.
+
+boot_scripts:
+
+ The name of U-Boot style boot.scr files that $bootcmd searches for.
+
+ Example: boot.scr.uimg boot.scr
+
+ (Typically we expect extlinux.conf to be used, but execution of boot.scr is
+ maintained for backwards-compatibility.)
+
+ Entries may be removed or re-ordered in this list to affect the set of
+ filenames which are supported.
+
+scan_dev_for_extlinux:
+
+ If you want to disable extlinux.conf on all disks, set the value to something
+ innocuous, e.g. setenv scan_dev_for_extlinux true.
+
+scan_dev_for_scripts:
+
+ If you want to disable boot.scr on all disks, set the value to something
+ innocuous, e.g. setenv scan_dev_for_scripts true.

+Specifying GPIO information for devices
+============================================
+
+1) gpios property
+-----------------
+
+Nodes that makes use of GPIOs should specify them using one or more
+properties, each containing a 'gpio-list':
+
+ gpio-list ::= <single-gpio> [gpio-list]
+ single-gpio ::= <gpio-phandle> <gpio-specifier>
+ gpio-phandle : phandle to gpio controller node
+ gpio-specifier : Array of #gpio-cells specifying specific gpio
+ (controller specific)
+
+GPIO properties should be named "[<name>-]gpios", with <name> being the purpose
+of this GPIO for the device. While a non-existent <name> is considered valid
+for compatibility reasons (resolving to the "gpios" property), it is not allowed
+for new bindings.
+
+GPIO properties can contain one or more GPIO phandles, but only in exceptional
+cases should they contain more than one. If your device uses several GPIOs with
+distinct functions, reference each of them under its own property, giving it a
+meaningful name. The only case where an array of GPIOs is accepted is when
+several GPIOs serve the same function (e.g. a parallel data line).
+
+The exact purpose of each gpios property must be documented in the device tree
+binding of the device.
+
+The following example could be used to describe GPIO pins used as device enable
+and bit-banged data signals:
+
+ gpio1: gpio1 {
+ gpio-controller
+ #gpio-cells = <2>;
+ };
+ gpio2: gpio2 {
+ gpio-controller
+ #gpio-cells = <1>;
+ };
+ [...]
+
+ enable-gpios = <&gpio2 2>;
+ data-gpios = <&gpio1 12 0>,
+ <&gpio1 13 0>,
+ <&gpio1 14 0>,
+ <&gpio1 15 0>;
+
+Note that gpio-specifier length is controller dependent. In the
+above example, &gpio1 uses 2 cells to specify a gpio, while &gpio2
+only uses one.
+
+gpio-specifier may encode: bank, pin position inside the bank,
+whether pin is open-drain and whether pin is logically inverted.
+Exact meaning of each specifier cell is controller specific, and must
+be documented in the device tree binding for the device. Use the macros
+defined in include/dt-bindings/gpio/gpio.h whenever possible:
+
+Example of a node using GPIOs:
+
+ node {
+ enable-gpios = <&qe_pio_e 18 GPIO_ACTIVE_HIGH>;
+ };
+
+GPIO_ACTIVE_HIGH is 0, so in this example gpio-specifier is "18 0" and encodes
+GPIO pin number, and GPIO flags as accepted by the "qe_pio_e" gpio-controller.
+
+1.1) GPIO specifier best practices
+----------------------------------
+
+A gpio-specifier should contain a flag indicating the GPIO polarity; active-
+high or active-low. If it does, the follow best practices should be followed:
+
+The gpio-specifier's polarity flag should represent the physical level at the
+GPIO controller that achieves (or represents, for inputs) a logically asserted
+value at the device. The exact definition of logically asserted should be
+defined by the binding for the device. If the board inverts the signal between
+the GPIO controller and the device, then the gpio-specifier will represent the
+opposite physical level than the signal at the device's pin.
+
+When the device's signal polarity is configurable, the binding for the
+device must either:
+
+a) Define a single static polarity for the signal, with the expectation that
+any software using that binding would statically program the device to use
+that signal polarity.
+
+The static choice of polarity may be either:
+
+a1) (Preferred) Dictated by a binding-specific DT property.
+
+or:
+
+a2) Defined statically by the DT binding itself.
+
+In particular, the polarity cannot be derived from the gpio-specifier, since
+that would prevent the DT from separately representing the two orthogonal
+concepts of configurable signal polarity in the device, and possible board-
+level signal inversion.
+
+or:
+
+b) Pick a single option for device signal polarity, and document this choice
+in the binding. The gpio-specifier should represent the polarity of the signal
+(at the GPIO controller) assuming that the device is configured for this
+particular signal polarity choice. If software chooses to program the device
+to generate or receive a signal of the opposite polarity, software will be
+responsible for correctly interpreting (inverting) the GPIO signal at the GPIO
+controller.
+
+2) gpio-controller nodes
+------------------------
+
+Every GPIO controller node must contain both an empty "gpio-controller"
+property, and a #gpio-cells integer property, which indicates the number of
+cells in a gpio-specifier.
+
+Example of two SOC GPIO banks defined as gpio-controller nodes:
+
+ qe_pio_a: gpio-controller@1400 {
+ compatible = "fsl,qe-pario-bank-a", "fsl,qe-pario-bank";
+ reg = <0x1400 0x18>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+ qe_pio_e: gpio-controller@1460 {
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1460 0x18>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+2.1) gpio- and pin-controller interaction
+-----------------------------------------
+
+Some or all of the GPIOs provided by a GPIO controller may be routed to pins
+on the package via a pin controller. This allows muxing those pins between
+GPIO and other functions.
+
+It is useful to represent which GPIOs correspond to which pins on which pin
+controllers. The gpio-ranges property described below represents this, and
+contains information structures as follows:
+
+ gpio-range-list ::= <single-gpio-range> [gpio-range-list]
+ single-gpio-range ::= <numeric-gpio-range> | <named-gpio-range>
+ numeric-gpio-range ::=
+ <pinctrl-phandle> <gpio-base> <pinctrl-base> <count>
+ named-gpio-range ::= <pinctrl-phandle> <gpio-base> '<0 0>'
+ gpio-phandle : phandle to pin controller node.
+ gpio-base : Base GPIO ID in the GPIO controller
+ pinctrl-base : Base pinctrl pin ID in the pin controller
+ count : The number of GPIOs/pins in this range
+
+The "pin controller node" mentioned above must conform to the bindings
+described in ../pinctrl/pinctrl-bindings.txt.
+
+In case named gpio ranges are used (ranges with both <pinctrl-base> and
+<count> set to 0), the property gpio-ranges-group-names contains one string
+for every single-gpio-range in gpio-ranges:
+ gpiorange-names-list ::= <gpiorange-name> [gpiorange-names-list]
+ gpiorange-name : Name of the pingroup associated to the GPIO range in
+ the respective pin controller.
+
+Elements of gpiorange-names-list corresponding to numeric ranges contain
+the empty string. Elements of gpiorange-names-list corresponding to named
+ranges contain the name of a pin group defined in the respective pin
+controller. The number of pins/GPIOs in the range is the number of pins in
+that pin group.
+
+Previous versions of this binding required all pin controller nodes that
+were referenced by any gpio-ranges property to contain a property named
+#gpio-range-cells with value <3>. This requirement is now deprecated.
+However, that property may still exist in older device trees for
+compatibility reasons, and would still be required even in new device
+trees that need to be compatible with older software.
+
+Example 1:
+
+ qe_pio_e: gpio-controller@1460 {
+ #gpio-cells = <2>;
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1460 0x18>;
+ gpio-controller;
+ gpio-ranges = <&pinctrl1 0 20 10>, <&pinctrl2 10 50 20>;
+ };
+
+Here, a single GPIO controller has GPIOs 0..9 routed to pin controller
+pinctrl1's pins 20..29, and GPIOs 10..19 routed to pin controller pinctrl2's
+pins 50..59.
+
+Example 2:
+
+ gpio_pio_i: gpio-controller@14B0 {
+ #gpio-cells = <2>;
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1480 0x18>;
+ gpio-controller;
+ gpio-ranges = <&pinctrl1 0 20 10>,
+ <&pinctrl2 10 0 0>,
+ <&pinctrl1 15 0 10>,
+ <&pinctrl2 25 0 0>;
+ gpio-ranges-group-names = "",
+ "foo",
+ "",
+ "bar";
+ };
+
+Here, three GPIO ranges are defined wrt. two pin controllers. pinctrl1 GPIO
+ranges are defined using pin numbers whereas the GPIO ranges wrt. pinctrl2
+are named "foo" and "bar".

+20. A little note about SPI uclass features:
+
+The SPI uclass keeps some information about each device 'dev' on the bus:
+
+ struct dm_spi_slave_platdata - this is device_get_parent_platdata(dev)
+ This is where the chip select number is stored, along with
+ the default bus speed and mode. It is automatically read
+ from the device tree in spi_child_post_bind(). It must not
+ be changed at run-time after being set up because platform
+ data is supposed to be immutable at run-time.
+ struct spi_slave - this is device_get_parentdata(dev)
+ Already mentioned above. It holds run-time information about
+ the device.
+
+There are also some SPI uclass methods that get called behind the scenes:
+
+ spi_post_bind() - called when a new bus is bound
+ This scans the device tree for devices on the bus, and binds
+ each one. This in turn causes spi_child_post_bind() to be
+ called for each, which reads the device tree information
+ into the parent (per-child) platform data.
+ spi_child_post_bind() - called when a new child is bound
+ As mentioned above this reads the device tree information
+ into the per-child platform data
+ spi_child_pre_probe() - called before a new child is probed
+ This sets up the mode and speed in struct spi_slave by
+ copying it from the parent's platform data for this child.
+ It also sets the 'dev' pointer, needed to permit passing
+ 'struct spi_slave' around the place without needing a
+ separate 'struct udevice' pointer.
+
+The above housekeeping makes it easier to write your SPI driver.
