Adding Tom too - I think he modified the OVMF reset vector lately and
might know.

I'm not an expert, but I think that OVMF has its own reset vector in
OvmfPkg/ResetVector, and therefore the changes in uefiCpuPkg will not
affect OVMF.
Regarding the patch itself:
(1) I suggest separating the python tooling changes to one patch,
verifying that the new python scripts generate the same binary files as
the original python scripts. Then add another patch which introduces
the reset vector changes.
(2) Do all x64 CPUs support 1 GB pages? Is it always enabled? Do we need
to check this capability somewhere?

>> X64 Reset Vector Code can access the memory range till 4GB using the Linear-Address Translation to a 2-MByte Page, when user wants to use more than 4G using 2M Page it will leads to use more number of Page table entries. using the 1-GByte Page table user can use more than 4G Memory by reducing the page table entries using 1-GByte Page, this patch attached can access memory range till 512GByte.
