Hello Alex,

I suggest to use the same values as the RISC-V branch of EDK2.
https://github.com/tianocore/edk2-staging/blob/RISC-V/MdePkg/Include/Uefi/UefiSpec.h#L2171

BOOTRISCV32.EFI
BOOTRISCV64.EFI

These values are not standardized yet. But we have not better hint of
what to expect in the next version of the spec.

Best regards

Heinrich
