[coreboot] uefi_nvs.bin in coreboot

[galla rao]

Hi Jose,

with uefipayload (tianocore) does the setup variables get saved?

Do we need any changes, I had older coreboot which comes from Intel and
also 4.8.1 (Both these payloads) does not save setup variables

change of boot order or secureboot->standara mode/custom mode, i tried some
of them

Do we need a change in CorebootPayloadPkg.fdf  for pointing to correct
NVStore Base Address, though gRT->SetVariable from the code works

Regards
Ranga
