[edk2] [RFC PATCH v2 08/10] OvmfPkg/QemuFwCfgLib: Provide Pei and Dxe specific library support

There is a newer version of this series
[edk2] [RFC PATCH v2 08/10] OvmfPkg/QemuFwCfgLib: Provide Pei and Dxe specific library support
Posted by Brijesh Singh 7 years, 8 months ago 
Current QemuFwCfgLib.inf is used in both Pei and Dxe phases. The patch adds
Pei and Dxe inf file to provide a seperate QemuFwCfg library for Pei and Dxe
phases. There is no code change in this patch other than rearranging the files
and updating inf files.

The patch is precursor to add SEV support in QemuFwCfgLib, When SEV guest is
enabled then in Pei phase we support IO operation but in Dxe phase we can
support both IO and DMA operations.

The PEI_CORE module type is not listed in any of the library instance
INF files, so this resolution is useless.

The rest looks OK to me.
