Summary: PCI Express Base PCD is UINT64, code should not thunk
to UINT32
Product: EDK2 Platforms
Version: Current
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal

There is a thunking operation from UINT64 to UINT32 for the PCI Express Base
address. if the PCIE base address is 32bit then there won't be a issue. but if
the PCIE base address then thunking the address will points to different junk
address which will fail the execution flow.
