Brijesh Singh 202fb22be6 OvmfPkg/SecMain: validate the memory used for decompressing Fv ... BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 The VMM launch sequence should have pre-validated all the data pages used in the Reset vector. The range does not cover the data pages used during the SEC phase (mainly PEI and DXE firmware volume decompression memory). When SEV-SNP is active, the memory must be pre-validated before the access. Add support to pre-validate the memory range from SnpSecPreValidatedStart to SnpSecPreValidatedEnd. This should be sufficent to enter into the PEI phase.
