Define all standard baudrates plus 3 non-standard high speed:
3125000 4000000 5150000
3125000 matches divisor 5 with 250 MHz TCLK and divisor 4 with 200 MHz TCLK.
4000000 is the rounded value for divisor 4 with 250 MHz TCLK (3906250) and
divisor 3 with 200 MHz TCLK (4166666).
5150000 is the rounded value (5208333) for divisor 3 with 250 MHz TCLK.
Testing showed that rounded value is more stable then exactly calculated.
And it is the highest possible baudrate which is stable on A38x platform.
Any other baudrate values above 2500000 are unstable, which is reason why
e.g. standard value 3000000 is not defined, and it is needed to use
non-standard value 3125000.

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

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

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

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.

Based on DT spec you can have one memory node which multiple ranges or
multiple nodes.
fdt_fixup_memory_banks() is not implemented in a correct way when multiple
memory nodes are present because all ranges are put it to the first memory
node found. And next memory nodes are kept in DT which ends up in the same
range specification in the same DT.
Here is what it is happening.
Origin DT.
memory@0 {
device_type = "memory";
reg = <0x0 0x0 0x0 0x80000000>;
};
memory@800000000 {
device_type = "memory";
reg = <0x8 0x00000000 0x0 0x80000000>;
};
After fdt_fixup_memory_banks()
memory@0 {
device_type = "memory";
reg = <0x0 0x0 0x0 0x80000000>, <0x8 0x00000000 0x0 0x80000000>;
};
memory@800000000 {
device_type = "memory";
reg = <0x8 0x00000000 0x0 0x80000000>;
};
As is visible memory@0 node got second range but there is still
memory@800000000 node present and 2G range is listed twice.
The solution can't be that second node is removed because it can be
referenced already that's why it is better for us to disable this option
for now.

Based on thread
https://lists.denx.de/pipermail/u-boot/2021-June/451828.html
especially
"Overall we have a deficiency in the UEFI implementation in that we
cannot deal with block devices added or removed after initialization."
there is a need to deal with removable media as usb/scsi/sata.
That's why bridge this gap in EFI implementation by resetting usb and
scsi resets to get all disks before efi_init_obj_list() is called.
In our standard boot flow, where we use distro boot, order is fixed as
"jtag mmc0 mmc1 qspi0 nand0 usb0 usb1 scsi0 pxe dhcp" with prioritizing
boot device added by commit 2882b39d56 ("arm64: zynqmp: Setup the first
boot_target at run time").
When device has ESP partition all devices should be detected because then
efi_disk_register() in efi_init_obj_list() is called only once.
The first such a device is sd/emmc(mmc0/mmc1) and then disks on usb/sata
are not handled at all.
The commit 6bb577dbb3 ("arm64: zynqmp: Disable
EFI_CAPSULE_ON_DISK_EARLY") also pointed out on this issue but detection of
removable media wasn't solved that's why do it now via preboot command.
I have tested cases without usb and scsi and there is no problem with
calling resets without devices itself.

As per SD spec when SD host controller is reset, it takes 1000msec
to detect the card state. In case, if we enable the sd bus voltage &
card detect state is not stable, then host controller will disable
the sd bus voltage.
In case of warm/subsystem reboot, due to unstable card detect state
host controller is disabling the sd bus voltage to sd card causing
sd card timeout error. So we wait for a maximum of 1000msec to get
the card detect state stable before we enable the sd bus voltage.
This current fix is workaround for now, this needs to be analysed
further. Zynqmp platform should behave the same as Versal, but we
did not encounter this issue as of now. So we are fixing it for
