New function should be called from board dram_init() because it initialized
gd->ram_base/ram_size. It finds the lowest available memory.
On systems with multiple memory nodes finding out the first memory node by
fdtdec_setup_mem_size_base() is not enough because this memory can be above
actual U-Boot VA mapping. Currently only mapping till 39bit is supported
(Full 44bit mapping was removed by commit 7985cdf74b ("arm64: Remove
non-full-va map code")).
If DT starts with the first memory node above 39bit address then system can
be unpredictable.
The function is available only when multiple memory bank support is
enabled.
Calling fdtdec_setup_memory_banksize() from dram_init() is not possible
because fdtdec_setup_memory_banksize() is saving dram information to bd
structure which is placed on stack but not initialized at this time. Also
stack is placed at location setup in dram_init().

Origin function was calling strsep which replaced delimiter ',' by a null
byte ('\0'). Operation was done directly on FDT which ends up with the
following behavior:
ZynqMP> printenv fdtfile
fdtfile=xilinx/zynqmp.dtb
ZynqMP> fdt addr $fdtcontroladdr
ZynqMP> fdt print / compatible
compatible = "xlnx", "zynqmp"
As is visible fdtfile was correctly composed but a null byte caused that
xlnx was separated from zynqmp.
This hasn't been spotted because in all Xilinx DTs there are at least 3
compatible string and only the first one was affected by this issue.
But for systems which only had one compatible string "xlnx,zynqmp" it was
causing an issue when U-Boot's DT was used by Linux kernel.
The patch removes strsep calling and strchr is called instead which just
locate the first char after deliminator ',' (variable called "name").
And using this pointer in fdtfile composing.

On system with PL DDR which is placed before PS DDR in DT
env_get_bootm_size() and env_get_bootm_low() without specifying bootm_low
and bootm_size variables are taking by default gd->bd->bi_dram[0].start and
gd->bd->bi_dram[0].size. As you see 0 means bank 0 which doesn't need to be
PS ddr and even can be memory above 39bit VA which is what U-Boot supports
now.
That's why setup bootm variables based on ram_base/ram_size setting to make
sure that boot images are placed to the same location as U-Boot is placed.
This location should be by default location where OS can boot from.

Under the current implementation, all the signatures, if any, in
a signed image must be verified before loading it.
Meanwhile, UEFI specification v2.8b section 32.5.3.3 says,
Multiple signatures are allowed to exist in the binary’s certificate
table (as per PE/COFF Section “Attribute Certificate Table”). Only
one hash or signature is required to be present in db in order to pass
validation, so long as neither the SHA-256 hash of the binary nor any
present signature is reflected in dbx.
This patch makes the semantics of signature verification compliant with
the specification mentioned above.
