[edk2-devel] [PATCH 1/2] OvmfPkg: Change SEV Launch Secret API to be UINT64 for base and size

[James Bottomley]

Although the SEV secret location must always be below 4GB, the same is
not necessarily true for Intel TDX, so change the configuration table
to contain a pair of UINT64 parameters instead of UINT32 so that any X64
location can be represented.

This represents an ABI change, so it is essential to get this in
before the next stable tag
