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.
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.

xilinx: Disable ARCH_FIXUP_FDT_MEMORY
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.

xilinx: zynqmp: Initialize usb and scsi via preboot
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 2882b39d564b ("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 6bb577dbb30f ("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.

Do not enable watchdog driver in default zynqmp configuration. The reason
is that not all distributions are handling watchdog properly and then

enable it by hand.

mmc: zynq_sdhci: Wait till sd card detect state is stable
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
Versal only.
