BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 The OvmfPkgX86 build reserves memory regions in MEMFD. The memory regions get accessed in the SEC phase. AMD SEV-SNP require that the guest's private memory be accepted or validated before access. Introduce a Guided metadata structure that describes the reserved memory regions. The VMM can locate the metadata structure by iterating through the reset vector guid and process the areas based on the platform specific requirements.
