It is hardware compatible with classic MicroBlaze processor.

Location of bootscript in flash can be specified via /options/u-boot DT
node by using bootscr-flash-offset and bootscr-flash-size properties.
Values should be saved to script_offset_f and script_size_f variables.
Variables are described in doc/develop/bootstd.rst as:
script_offset_f
SPI flash offset from which to load the U-Boot script, e.g. 0xffe000
script_size_f
Size of the script to load, e.g. 0x2000

The bootscript is expected at a default address specific to each
platform.
When high speed memory like Programmable Logic Double Data Rate RAM
(PL DDR RAM) or Higher Bandwidth Memory RAM (HBM) is used the boot.scr
may be loaded at a different offset. The offset needs to be set through
setenv. Due to the default values in some cases the boot.scr is falling
in between the kernel partition.
The bootscript address or the bootscript offset is fetched directly from
the DT and updated in the environment making it easier for automated
flows.

FRU data is not displayed properly in case of 0xc1 fields.
The 0xC1 can be used in two cases.
1. Char record type 8-bit ASCII + Latin 1 with length of 1.
(For example board revision 'A')
2. C1h (type/length byte encoded to indicate no more info fields).
which can follow by 00h to fill all remaining unused space
Hence removed the check end-of-the field c1 to allow c1 fields.
"ASCII+LATIN1" is defined as the printable characters from the
first set of 256 characters of Unicode 6.2 (U+0000h through U+00FFh,
inclusive) expressed as an eight-bit value. (Unicode follows ISO/IEC
8859-1 in the layout of printable characters up to U+00FFh).
So, print only printable chars and limit range from 0x20 ' ' to 0x7e '-'
which will be also indication if 0xc1 behaves as record with one char or

only description with this name is selected.

by this fragment.
Xilinx normally have some board revisions which are SW compatible to each

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.

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.
