ofnode_read_bootscript_flash() reads bootscript address from
/options/u-boot DT node. bootscr-flash-offset and bootscr-flash-size
properties are read and values are filled. When bootscr-flash-size is not
defined, bootscr-flash-offset property is unusable that's why cleaned.
Both of these properties should be defined to function properly.
Also add test to cover this new function.

Now that the zynqmp pinctrl driver supports the tri-state registers, make
sure that the pins requiring output-enable are configured appropriately for
SOMs.
Without it, all tristate setting for MIOs, which are not related to SOM
itself, are using default configuration which is not correct setting.
It means SDs, USBs, ethernet, etc. are not working properly.
In past it was fixed through calling tristate configuration via bootcmd:
usb_init=mw 0xFF180208 2020
kv260_gem3=mw 0xFF18020C 0xFC0 && gpio toggle gpio@ff0a000038 && \
gpio toggle gpio@ff0a000038

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.

ofnode_read_bootscript_address() reads bootscript address from
/options/u-boot DT node. bootscr-address or bootscr-ram-offset properties
are read and values are filled. bootscr-address has higher priority than
bootscr-ram-offset and the only one should be described in DT.

There is a chance that assigned-clock-rates is given and assigned-clocks
could be empty. Dont return error in that case, because the probe of the
corresponding driver will not be called at all if this fails.

Kernel Address Space Layout Randomization (KASLR) is a hardening
feature that aims to make it more difficult to take advantage
of known exploits in the kernel, by placing kernel data
structures at a random address at each boot.The bootloader
supports randomizing the virtual address at which the kernel image
is loaded. The bootloader must provide entropy by passing a random
u64 value in the /chosen/kaslr-seed device tree node.
When we run "kaslrseed" command from U-Boot, the bootloader will
genarate the kaslr-seed and update the /chosen/kaslr-seed DT property.

All si570 mgt chips have factory default 156.25MHz but DT changed it to
148.5MHz. After tracking it is pretty much c&p fault taken from Zynq
zc702/zc706 boards where 148.5MHz was setup as default because it was
requirement for AD7511 chip available on these boards.
ZynqMP board don't contain this chip that's why factory default frequency
can be used.

HBM stands for high bandwidth memory and is a type of memory interface used
in 3D-stacked DRAM (dynamic random access memory) in some AMD GPUs (aka
graphics cards), as well as the server, high-performance computing (HPC)
and networking and client space. High Bandwidth Memory(HBM) has total 16
channels, one channel is divided into two pseudo channels which makes its
32 banks each with some amount of memory.
And then we have DDR_LOW PS low, DDR_HIGH0 PS high, DDR_HIGH1 PS very high
and pretty much there should be also place for PL DDR. So maximum number of
memory banks will be 36, updating the CONFIG_NR_DRAM_BANKS to 36.
