[edk2-devel] [PATCH 1/1] ArmPkg/SmbiosMiscDxe: use UINT64 for BiosPhysicalSize

["Leif Lindholm" <quic_llindhol@quicinc.com>]

The top two bits of the Extended BIOS ROM Size field indicates the unit
used for the remaining 14 bits. If the size is greater than 16GB, the
unit is gigabytes.
The test for this uses the local BiosPhysicalSize variable, which is a
UINTN, meaning that when building for a 32/bit architecture (ARM) with
CLANGDWARF we have a tautological constant comparison, which the toolchain
flags now we've stopped disabling that warning.
So switch the BiosPhysicalSize variable to UINT64.

Ultimately, the size is still restricted to 32-bit since it is set
directly from a PcdGet32 (PcdFvSize). This should ideally be broken
out into an OemMiscLib function since PcdFvSize is fundamentally an
ArmPkg concept.
