First, we convert CONFIG_SYS_I2C_LEGACY to Kconfig.  Next, as you cannot
have SYS_I2C_LEGACY and DM_I2C at the same time, introduce
CONFIG_SPL_SYS_I2C_LEGACY so that we can enable the legacy option only
in SPL.  Finally, for some PowerPC cases we also need
CONFIG_TPL_SYS_I2C_LEGACY support.  Convert all of the existing users to
one or more symbols.

This platform defines everything needed to be able to use the
eeprom command.  In addition, board/compulab/common/eeprom.c is required
by the platform, and does not use CONFIG_ID_EEPROM to enable/disable
builing of it.  In order to migrate CONFIG symbols to Kconfig and to not
have to add complex logic to handle this case, enable CMD_EEPROM on this
board.

There is no space in OCM for SPL stack because the space in OCM is occupied
by TF-A. That's why move relocate stack to DDR to 0x18000000 address
and also enable SPL_SIZE_LIMIT not to be more then 0xfffea000 which is
default address for TFA.

It is good to summarize current DDR usage in SPL flow.
0-0x80000 is used for BSS
 (CONFIG_SPL_BSS_START_ADDR, CONFIG_SPL_BSS_MAX_SIZE)
0x100000 is used for DTB passing address
 (CONFIG_XILINX_OF_BOARD_DTB_ADDR)
0x17fffe70 - CONFIG_SPL_STACK_R_ADDR - is used for GD
0x18000000 is used for SPL stack
 (CONFIG_SPL_STACK_R_ADDR)
0x20000000-0x21000000 is used for SPL malloc area
 (CONFIG_SYS_SPL_MALLOC_START, CONFIG_SYS_SPL_MALLOC_SIZE)

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.

When MULTI_DTB_FIT is enabled fit-dtb.blob fit image is created which
contain all DTBs listed by CONFIG_OF_LIST. And with DTB_RELESELECT there is
a need to handle it as one file with DTBs in it not as separate DTBs in
u-boot.its/itb.
That's why extend mkimage_fit_atf.sh to generate u-boot.itb correctly.

Enabling MULTI_DTB_FIT and DTB_RESELECT can end up with multi DTBs in FIT
image placed and aligned only by 32bits (4bytes). Based on device tree
specification:
"Specifically, the memory reservation block shall be aligned to an 8-byte boundary
and the structure block to a 4-byte boundary."
is 64bit (8bytes) alignment required. That's why make sure that
fit-dtb.blob and u-boot.itb as our primary target images for Xilinx ZynqMP
are all 64bit aligned.

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.
