xilinx: Setup bootm variables
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.

Multiple signatures are allowed to exist in the binary’s certificate

There may be a chance that board specific fix_fdt() will change the
size of FDT blob so it's safe to call reserve_fdt() after fix_fdt()
otherwise global data (gd) will overwrite with FDT blob values.

riscv: additional crash information
If an exception occurs, the relocated program counter and return address
are required for an analysis.
With this patch you get:
=> exception undefined
Unhandled exception: Illegal instruction

We can use the relocated addresses to find the involved functions in
u.boot.map:
.text.do_undefined

.text.cmd_process

If an exception occurs in an UEFI binary additionally the load addresses of
the UEFI binaries are needed. With this patch:

cmd: exception: unaligned data access on RISC-V
The command 'exception' can be used to test the handling of exceptions.
Currently the exception command only allows to create an illegal
instruction exception on RISC-V.
Provide a sub-command 'exception unaligned' to cause a misaligned load
address exception.
Adjust the online help for 'exception undefined'.
