Thanks a lot for tackling this problem - it's been on the back burner 
for way too long :). Unfortunately this patch set loads grub via UEFI, 
but then does not execute Linux using the UEFI protocol. While that's a 
nice hack for starters, it severely limits the extensibility of the boot 
flow going forward.

IIRC either Anup or Atish wanted to work on a UEFI boot stub for Linux. 
We could then just unify the ARM and RISC-V UEFI boot paths in grub and 
use that common code to run Linux via the UEFI stub.


Thanks,

Alex
