[edk2-devel] [PATCH v2 15/16] UefiCpuPkg: CpuIo2Smm: Support of CpuIo driver under StandaloneMm
Kun Qin
kun.q at outlook.com
Tue Jan 5 18:59:34 UTC 2021
This change added support of CpuIo driver under StandaloneMm. The core
services switched to gMmst based instead of gMmst. It also abstracts
standalone and traditional MM driver entrypoints into separate files to
allow maximal common implementations.
