[edk2-devel] [PATCH 5/5] UefiPayloadPkg: Add support for Firmware Volume Block Protocol

[Guo Dong]

I think these questions could be answered in the attached email which I replied to Rudolph for similar questions.

Thanks,
Guo

Looks like for Guo's patch SMMSTORE driver is not needed since it implements a SpiFlashLib for accessing the SPI Flash controller (via hardware sequencer) of Intel CPU targets...
But this is for Universal Payload only right? I guess coreboot supports only the non-universal mode.
This stuff was tested only in SBL right?

Hey Guo

To have the parselib and not SMMSTORE support is a bit of a paradox; coreboot isn't fully functional without one. I think moving this and any subsequent patches into edk2-platforms will inevitably lead to forks, which isn't beneficial to anyone.

Is there any method (or ideally exception ;) ) you can suggest for allowing bootloader specific patches?

Many thanks

Sean
