The examples, broadly speaking, do not run out of the box since they
assume an address to be loaded in to memory at and run from, rather than
a Kconfig entry. The next problem for RISC-V is that, well, there's no
api/api_platform-riscv.c file (and forever ago I steered people away
from adding that and instead adding EFI support, the patches are in
patchwork somewhere).
