 Booting Options
 ---------------

 NB: The reference manual documents the RCW source with the *least-significant
 bit first*.

 QSPI boot
 ^^^^^^^^^

 This is the default. ``{ SW5[0:8], SW4[0] }`` should be ``0010_0010_0``.

 SD boot and eMMC boot
 ^^^^^^^^^^^^^^^^^^^^^

 ``{ SW5[0:8], SW4[0] }`` should be ``0010_0000_0``. eMMC is selected only if
 there is no SD card in the slot.

 .. _ls1046ardb_jtag:

 JTAG boot
 ^^^^^^^^^

 To recover a bricked board, or to perform initial programming, the ls1046
 supports using two hard-coded Reset Configuration Words (RCWs). Unfortunately,
 this configuration disables most functionality, including the uarts and ethernet.
 However, the SD/MMC and flash controllers are still functional. To get around
 the lack of a serial console, we will use ARM semihosting instead. When
 enabled, OpenOCD will interpret certain instructions as calls to the host
 operating system. This allows U-Boot to use the console, read/write files, or
 run arbitrary commands (!).

 When configuring U-Boot, ensure that ``CONFIG_SEMIHOSTING``,
 ``CONFIG_SPL_SEMIHOSTING``, and ``CONFIG_SEMIHOSTING_SERIAL`` are enabled.
 ``{ SW5[0:8], SW4[0] }`` should be ``0100_1111_0``. Additionally, ``SW4[7]``
 should be set to ``0``. Connect to the "console" USB connector on the front of
 the enclosure.

 Create a new file called ``u-boot.tcl`` (or whatever you choose) with the
 following contents::

     # Load the configuration for the LS1046ARDB
     source [find board/nxp_rdb-ls1046a.cfg]
     # Initialize the scan chain
     init
     # Stop the processor
     halt
     # Enable semihosting
     arm semihosting enable
     # Load U-Boot SPL
     load_image spl/u-boot-spl 0 elf
     # Start executing SPL at the beginning of OCRAM
     resume 0x10000000

 Then, launch openocd like::

     openocd -f u-boot.tcl

 You should see the U-Boot SPL banner followed by the banner for U-Boot proper
 in the output of openocd. The CMSIS-DAP adapter is slow, so this can take a
 long time. If you don't see it, something has gone wrong. After a while, you
 should see the prompt. You can load an image using semihosting by running::

     => load hostfs - $loadaddr <name of file>

 Note that openocd's terminal is "cooked," so commands will only be sent to
 U-Boot when you press enter, and all commands will be echoed twice.
 Additionally, openocd will block when waiting for input, ignoring gdb, JTAG
 events, and Ctrl-Cs. To make openocd process these events, just hit enter.

 Using an external JTAG adapter
 """"""""""""""""""""""""""""""

 The CMSIS-DAP adapter can be rather slow. To speed up booting, use an external
 JTAG adapter. The following examples assume you are using a J-Link, though any
 adapter supported by OpenOCD will do. Ensure that ``SW4[7]`` is ``1``. Attach
 your jtag adapter to J22. Modify ``u-boot.tcl`` and replace the first two lines
 with the following::

     # Load the J-Link configuration (or whatever your adapter is)
     source [find interface/jlink.cfg]
     # Use JTAG, since the J-Link also supports SWD
     transport select jtag
     # The reset pin resets the whole CPU
     reset_config srst_only
     # Load the LS1046A config
     source [find target/ls1046a.cfg]

 You can proceed as normal through the rest of the steps above. I got a speedup
 of around 100x by using a J-Link.

 Debug UART
 ----------

 To enable the debug UART, enable the following config options::

     CONFIG_DEBUG_UART_NS16550=y
     CONFIG_DEBUG_UART_BASE=0x21c0500
     CONFIG_DEBUG_UART_CLOCK=300000000
