Changes in V2:
- Fixed instances where the new PPI was incorrectly reffered to as
"EDKII PEI Variable Protocol"
- Added OPTIONAL to the Attributes argument of GetVariable()
- Added description of initial calling conditions to GetNextVariableName()
- Clarified the function and format of EFI_AUTHENTICATED_VARIABLE_HOB
This patch series proposes a new architectural PPI: EDKII_PEI_VARIABLE_PPI
This PPI provides services to read and write to UEFI variables during the PEI
environment. While an implementation of this PPI does not exist yet, Intel is
working on a new implementation of the PEI variable services that includes write
support.
As this is essentially a PEI version of the EFI_SMM_VARIABLE_PROTOCOL, I don't
expect it to be immensely controversial. Regardless, before this implementation
is done, we would like to provide the community with an opportunity to provide
input the on new architectural PPI.
