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.

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.

The StarFive VisionFive 2 board cannot load spl/u-boot-spl.bin but needs a
prefixed header. We have referring to a vendor tool (spl_tool) for this
task. 'mkimage -T sfspl' can generate the prefixed file.
Use binman to invoke mkimage for the generation of file
spl/u-boot-spl.bin.normal.out.

The constants to define the idle state of SERDES MUX were defined in
bindings header. They are used only in DTS and driver uses the dt property
to set the idle state making it unsuitable for bindings.
The constants are moved to header next to DTS ("arch/arm/boot/dts/")
and all the references to bindings header are removed.
So add a warning to mark this bindings header as deprecated.
We could probably drop this header, but let us wait for kernel to
