This series starts with some fixes for backtraces for bugs found
when tracing with riscv EFI builds. The series then brings EFI
support to riscv, basing the approach heavily on arm64's support
(including arm64's improvements[1]). It should now be possible
to launch tests from EFI-capable bootloaders.

Thanks,
