I know a new version is coming up, but one comment still:
you should please make this series bisectable. That is, the series
should build at every stage.
That implies the following approach (each step below corresponds to a
patch, or to a sequence of patches):
- introduce the new library (class and instance(s)) first, in isolation;
this will duplicate the internal functions of SecureBootConfigDxe
- add lib class resolution(s) to all platforms in edk2 (and
edk2-platforms, possibly) that include SecureBootConfigDxe
- replace the internal functions of SecureBootConfigDxe with the new
Right now, ArmVirtPkg platforms will definitely not build against your
patch set applied up to and including only patch#1, because at patch#1,
SecureBootConfigDxe depends on SecureBootVariableLib, but ArmVirtPkg
doesn't yet resolve that lib class to any instance.
Also, I don't see any OvmfPkg patch in the series... hm, well, there are
OvmfPkg modifications, but they have been squashed into patch#3, "Intel
Platforms: add SecureBootVariableLib class resolution".
Regardless of whether we call OvmfPkg an "Intel Platform" -- I wouldn't,
BTW --, OvmfPkg DSC updates need to go in their own, isolated patch.
Same for EmulatorPkg -- separate patch please.
