[v2] ArmVirtPkg, OvmfPkg: factor out QemuFwCfgS3Lib

[edk2] [PATCH v2 05/12] OvmfPkg: resolve QemuFwCfgS3Lib
Posted by Laszlo Ersek 7 years, 7 months ago
QemuFwCfgS3Enabled() in "OvmfPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c"
queries the "etc/system-states" fw_cfg file.

The same implementation is now available factored-out in
"OvmfPkg/Library/QemuFwCfgS3Lib/QemuFwCfgS3PeiDxe.c". It is available to
PEIMs through the PeiQemuFwCfgS3LibFwCfg instance, and to DXE_DRIVER and
DXE_RUNTIME_DRIVER modules through the DxeQemuFwCfgS3LibFwCfg instance.

Resolve QemuFwCfgS3Lib accordingly.
