Dov Murik d10ad8444f OvmfPkg/QemuKernelLoaderFsDxe: call VerifyBlob after fetch from fw_cfg ... In QemuKernelLoaderFsDxeEntrypoint we use FetchBlob to read the content of the kernel/initrd/cmdline from the QEMU fw_cfg interface. Insert a call to VerifyBlob after fetching to allow BlobVerifierLib implementations to add a verification step for these blobs. This will allow confidential computing OVMF builds to add verification mechanisms for these blobs that originate from an untrusted source (QEMU). The null implementation of BlobVerifierLib does nothing in VerifyBlob, and therefore no functional change is expected.
