8174cd2116 xilinx: common: Add support for partial string match in board_fit_config_name_match()
Board name in FIT image can use U-Boot regular expressions SLRE to instruct
U-Boot to handle all revisions for certain board.
For example when name (description property) is saying "zynqmp-zcu104-revA"
only description with this name is selected.
When zynqmp-zcu104.* is described then all board revisions will be handled
by this fragment.
Xilinx normally have some board revisions which are SW compatible to each
other. That's why make sense to define board name with revisions first
follow by generic description with '.*' at the end like this:

config_1 {
        description = "zynqmp-zcu104-rev[AB]";
        fdt = "zynqmp-zcu104-revA";
};
config_2 {
        description = "zynqmp-zcu104.*";
        fdt = "zynqmp-zcu104-revC";
};

39d3c3cfaa xilinx: common: Add support for SOC detection
Code supports board detection based on information available in EEPROM in
legacy or FRU format. But this is not enough for emulation and simulation
systems which are lacking these identification EEPROMs. But SOC itself has
normally registers for SOC identification. Based on them it is possible to
compose detected name. That's why prepare infrastructure in common location
for SOC platform detection which is called before board platform detection.
SOC platform detection shouldn't detect real silicon and should fallback to
current existing mechanism to identify boards based on EEPROMs.

a32c3e9e4f arm64: xilinx: Move board_get_usable_ram_top() to common location
The commit ce39ee28ec ("zynqmp: Do not place u-boot to reserved memory
location") adds functionality for ZynqMP to read reserved memory node and
do not place U-Boot to reserved location. This functionality is generic
across all Xilinx SOCs that's why move it to common location to be used by
all Xilinx SOCs.

On zynq platform this is also fixing issue where U-Boot was placed to
locating which was reserved already which ends up with error message
"ERROR: reserving fdt memory region failed (addr=30000000 size=10000000
flags=4)" which is shown when bdinfo is called.

Tested on vck190, zcu102, zc706 and kc705 to cover all platforms.

UUID is already recorded when FRU is parsed but it is not copied to local

Data is saved in binary format but there must be conversion to string for
exporting it to variable and string should be in uuid format too.

e7fb789612 sandbox: Remove OF_HOSTFILE
OF_HOSTFILE is used on sandbox configs only.  Although it's pretty
unique and not causing any confusions,  we are better of having simpler
config options for the DTB.

So let's replace that with the existing OF_BOARD.  U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

52ff1626cf xilinx: common: Enabling generic function for DT reselection
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.

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

05af4834ad xilinx: Consolidate board_fit_config_name_match() for Xilinx platforms
Move board_fit_config_name_match() from Zynq/ZynqMP to common location.
This change will open a way to use it also by Microblaze and Versal.
Through this function there is a way to handle images with multiple DTBs.
For now match it with DEVICE_TREE as is done for Zynq.

d388cedd46 xilinx: Add DDR base address to bootscript address
Add ram base address to scriptaddr env variable to make boot
script address to be a valid address when ddr base address changes.

This works properly if the first memory region is the region where uboot
runs. Also the solution was taken in respect of a lot of jtag script
putting u-boot script to certain address. For standard cases
bd->bi_dram[0].start is 0 all the time. Only for systems with DDR placed
out of this location it does calculation.

This is not the best solution and should be done differently in future but
enough for now till we don't have full solution ready yet.

The most of Xilinx evaluation boards have FMC connectors which contain

Also generate cardX_ variables for easier script handling.

d61728c8e8 xilinx: board: Read the whole eeprom not just offset
Starts to use new way how eeproms should be referenced.
Reference is done via nvmem alias nodes. When this new way is specified
code itself read the eeprom and decode xilinx legacy format and fill struct
xilinx_board_description. Then based on information present there board_*
variables are setup.
If variables are saved and content can't be changed information is just
shown on console.

e2572b5544 xilinx: common: Do not save fdt_blob to bss section
For SPL flow without specifying address for DT loading DTB is automatically
appended behind U-Boot code. Specifically _end symbol is used. Just behind
it there is place for bss section.
It means if early code is using static variable and there is a write to
this variable DTB file is corrupted if variable is located between DTB
start and end.
In this particular case offset of this variable from bss section start is
very small (0x40) that's why DT is currupted which breaks this boot flow.

2570cc6430 xilinx: common: Change bootm_size variable setting
Linux kernel for arm32 requires dtb and initrd to be placed in low memory
to work properly. This requirement is described in chapter 4b) and 5) in
Linux documentation (Documentation/arm/booting.rst).

There is an issue on arm32 with 2GB of memory that bootm_size is bigger
than Linux lowmem (for example with VMSPLIT_3G). That's why limit bootm
size on these systems not to be above 768MB.

c8da6513c0 xilinx: Setup bootm variables
On system with PL DDR which is placed before PS DDR in DT
env_get_bootm_size() and env_get_bootm_low() without specifying bootm_low
and bootm_size variables are taking by default gd->bd->bi_dram[0].start and
gd->bd->bi_dram[0].size. As you see 0 means bank 0 which doesn't need to be
PS ddr and even can be memory above 39bit VA which is what U-Boot supports
now.
That's why setup bootm variables based on ram_base/ram_size setting to make
sure that boot images are placed to the same location as U-Boot is placed.
This location should be by default location where OS can boot from.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.
