U-Boot support board detection at run time and based on it change DT.
This feature is implemented for SOM Kria platforms which contain two
eeproms which contain information about SOM module and CC (Carrier card).
Full U-Boot starts with minimal DT file defined by
CONFIG_DEFAULT_DEVICE_TREE which is available in multi DTB fit image.
It is using default setup of board_name variable initializaed to
DEVICE_TREE which corresponds to CONFIG_DEFAULT_DEVICE_TREE option.
When DTB_RESELECT is enabled board_detection() is called. Keep it your mind
that this code is called before relocation. board_detection() is calling
xilinx_read_eeprom() which fills board_info (xilinx_board_description)
structure which are parsed in board_name_decode().
Based on DT configuration and amount of nvmemX aliases name of the board is
composed by concatenating CONFIG_SYS_BOARD "-" <board_name> "-rev"
<board_revision> "-" <cc_name> "-rev" <cc_revision>.
If CC is not present or more are available it keeps going.
When board name is composed and returned from board_name_decode() it is
assigned to board_name variable which is used by
board_fit_config_name_match() which is called via fdtdec_setup() when it
goes over config options in multi dtb FIT image.
From practical point of view multi DTB image is key point here which has to
contain configs for detected combinations. Unfortunately as of now they
have to be full DTBs and DTBOs are not supported.
That's why configuration like:
config_X {
description = "zynqmp-board-cc";
fdt = "board", "cc";
};
needs to be squashed together with:
fdtoverlay -o zynqmp-board-cc -i arch/arm/dts/zynqmp-board.dtb \
arch/arm/dts/zynqmp-cc.dtbo
and only one dtb is in fit:
config_X {
description = "zynqmp-board-cc";
fdt = "board-cc";
};
For creating multi DTBs fit image use mkimage -E, e.g.:
mkimage -E -f all.its all.dtb
When DTB_RESELECT is enabled xilinx_read_eeprom() is called before
relocation and it uses calloc for getting a buffer. Because this is dynamic
memory it is not relocated that's why xilinx_read_eeprom() is called again
as the part of board_init(). This second read with calloc buffer placed in
proper position board_late_init_xilinx() can setup u-boot variables as
before.

DT needs to be 64bit aligned. If it is not fdt64_to_cpu will fail when try

Add support for changing DT at run time. It is done via board_detection()
which returns platform_id and platform_version which can be used via

with DT which is should be used.

Use variable which points to DEVICE_TREE by default. The reason for this
change is to enable DTB_RESELECT and MULTI_DTB_FIT where board detection
can be used for change DTB at run time. That's why there must be reference
in board_fit_config_name_match() via variable instead of hardcoding it
which is sufficient for that use case.

The main reason for this to be implemented is capsule update.
Two memories are supported and tested which is MMC FAT based and QSPI
based.
For creating capsule these commands are used:
./tools/mkeficapsule --raw spl/boot.bin --index 1 capsule1.bin
./tools/mkeficapsule --raw u-boot.itb --index 2 capsule2.bin
Then transfer to SD card where these commands run:
load mmc 0 10000000 capsule1.bin
efidebug capsule update -v 10000000
load mmc 0 10000000 capsule2.bin
efidebug capsule update -v 10000000
Depends on the boot device used are binaries loaded to qspi or mmc fat
partition.
Also multiboot register is handled to make sure that the same location(id)
is used as image which is upgraded.
Two locations are used by purpose for SPL flow. If only boot.bin is used
create only one capsule.

Currently u-boot supports addresses upto 39-bits only. If anybody
wants to use addresses of more than 39-bits in Linux they will have
a separate memory node in DT. In such cases they will have multiple
memory nodes.
Currently u-boot selects and runs on lower memory bank region.
But bootscript is being loaded on dram bank 0, where dram bank 0 will
point to 1st memory node in DT. If first memory node is mentioned as
higher ddr(>39-bits address) then u-boot cannot load the bootscript.
So fix this issue by setting bootscript address within the lower memory
bank region.

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:

- reset_cpu(argvalue)
