c85a6b79d1 tools: mkimage: Extend mkimage to also include pmufw
The patch is adding external pmufw "Platform Management Unit firmware"
to boot.bin image. Boot.bin is a Xilinx format which bootrom is capable
to read and boot the system. pmufw is copied to the header data section
follows by u-boot-spl.bin. pmufw is consumed by PMU unit (Microblaze)
and SPL runs on a53-0.

This is generated command line when PMUFW_INIT_FILE is setup.

f322ad604e arm64: zynqmp: mp: Correct the R5 release sequence
This patch corrects the R5 release sequence by adding the
below steps.
1. Flush dcache to ensure that image loaded into memory.
2. Keep R5 reset just to ensure R5 in reset.
3. Disable caches before accessing TCM as with out this
   A53 can do speculative and may result in ECC failures
   if TCM's are not initialized. So, it is always better
   to disable dcaches before accessing TCM and enable back.

e3fdf5d056 arm64: zynqmp: spl: fix dual SD controller support
When enabling both SDHCI controllers, spl_mmc.c would actually choose
device sdhci0 even if booted from sdhci1 (boot_device). This is because
spl_mmc_get_device_index(boot_device) expects BOOT_DEVICE_MMC2[_2] in
order to return index 1 instead of 0.

The #if defined(...) statement is copied from board/xilinx/zynqmp/zynqmp.c

So the key to properly enabling both controllers as boot sources is
defining both CONFIG_ZYNQ_SDHCI0 and CONFIG_ZYNQ_SDHCI1 in your board's
include/configs/*.h.

3b6460809c tools: mkimage: Add support for initialization table for Zynq and ZynqMP
The Zynq/ZynqMP boot.bin file contains a region for register initialization
data. Filling in proper values in this table can reduce boot time
(e.g. about 50ms faster on QSPI boot) and also reduce the size of
the SPL binary.

The table is a simple text file with register+data on each line. Other
lines are simply skipped. The file can be passed to mkimage using the
"-R" parameter.

It is recommended to add reg init file to board folder.
For example:
CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int

2b1cdafa9f common: Pass the boot device into spl_boot_mode()
The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.

The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

stays at the same location all the time.
