We have moved most of our RISC-V implementation to edk2-platforms now, only the
absolute minimum is in edk2, already merged.
All other patches going into edk2-platforms have already been merged, these are new.
The first adds opensbi as a submodule. We wanted to have it reviewed because it
would be the first submodule in the edk2-platforms repository. Is that okay?
Since we are now running PEI in addition to DXE in S-Mode (like Ring 3 in x86),
we need to call into the SBI interface. The new library provides an interface
for EDK2 code to do that. It just wraps the ecall assembly instruction as a C
interface with EDK2-style return codes.
