Brijesh Singh 63c50d3ff2 OvmfPkg/ResetVector: cache the SEV status MSR value in workarea ... BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3582 In order to probe the SEV feature the BaseMemEncryptLib and Reset vector reads the SEV_STATUS MSR. Cache the value on the first read in the workarea. In the next patches the value saved in the workarea will be used by the BaseMemEncryptLib. This not only eliminates the extra MSR reads it also helps cleaning up the code in BaseMemEncryptLib.
