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.

FRU spec expected \0 for unused symbols but unfortunately a lot of boards
are using spaces instead of \0. That's why after saving it to desc->name
name is checked again and all spaces are converted to \0. This will ensure
that names can be used for string manipulations like concatenation.

The commit 573a3811ed ("sysreset: psci: support system reset in a generic

been reflected in usage message and user has to look at the code how to run
it. That's why update usage text to make this clear.

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
Versal only.

Host driver should explicitly request DLL reset before ITAP (assert DLL)

The DDR subsystem in Diamond Mesa is consisted of controller, PHY,

is come from DDR handoff data in bitstream, which contain the register
base addresses and user settings from tool.
Configuration settings of memory clock manager is come from the HPS
handoff data in bitstream, however the register base address is defined
in device tree.
The calibration is fully done in HPS, which requires IMEM and DMEM
binaries loading to PHY SRAM for running this calibration, both
IMEM and DMEM binaries are also part of bitstream, this bitstream
would be loaded to OCRAM by SDM, and configured by DDR driver.
