[edk2-devel] [PATCH v5 02/11] OvmfPkg/AmdSev: use GenericQemuLoadImageLib in AmdSev builds

[Dov Murik]

Newer kernels support efistub and therefore don't need all the legacy
stuff in X86QemuLoadImageLib, which are harder to secure.  Specifically
the verification of kernel/initrd/cmdline blobs will be added only to
the GenericQemuLoadImageLib implementation, so use that for SEV builds.
