In commit db27e9f3d8 ("OvmfPkg/LegacyRegion: Support legacy region
manipulation of Q35", 2016-03-15), Ray extended the
OvmfPkg/Csm/CsmSupportLib PAM register manipulation to Q35. However, we
missed that the same should be done to the QemuVideoDxe VBE Shim as well.
The omission has caused no problems in practice on Q35, because QEMU has
let us write to the ROM area, regardless of the PAM1 setting, all this
time. This has now changed with recent QEMU commit 208fa0e43645 ("pc: make
'pc.rom' readonly when machine has PCI enabled", 2017-07-28). The QEMU
commit exposes the OVMF bug when Windows 7 is started on Q35, using QEMU
2.10 -- the VBE Shim is no longer put in place and Windows 7 cannot find
it.
To remedy this, assign the "Pam1Address" local variable a PciLib address
that matches the board type (i440fx vs. q35).
Regarding the PcdLib dependency: QemuVideoDxe already uses PcdLib, both
directly (see "PcdDriverSupportedEfiVersion") and indirectly (e.g. via the
DxePciLibI440FxQ35 PciLib instance). Add PcdLib to [LibraryClasses] for
completeness.

* Introduce the PIIX4_PAM* and MCH_PAM* macros under
"OvmfPkg/Include/IndustryStandard". These macros capture the PAM
register offsets (in PCI config space) on the respective Memory
Controller B/D/F, from the respective data sheets.
* Under IndustryStandard, introduce the PMC_REGISTER_PIIX4() macro for
PIIX4. (For Q35, we already have DRAMC_REGISTER_Q35().) In both cases,
the B/D/F is 0/0/0.
* Under CsmSupportLib, replace the "PAMRegOffset" field (UINT8) in the
PAM_REGISTER_VALUE structure with "PAMRegPciLibAddress" (UINTN). The new
field contains the return value of the PCI_LIB_ADDRESS() macro.
* Under CsmSupportLib, replace the "mRegisterValues440" elements as
follows:
REG_PAMx_OFFSET_440, ReadEnableData, WriteEnableData
-->
PMC_REGISTER_PIIX4 (PIIX4_PAMx), ReadEnableData, WriteEnableData
* Under CsmSupportLib, replace the "mRegisterValuesQ35" elements as
follows:
REG_PAMx_OFFSET_Q35, ReadEnableData, WriteEnableData
-->
DRAMC_REGISTER_Q35 (MCH_PAMx), ReadEnableData, WriteEnableData
* Under CsmSupportLib, update the register address calculations as follows
(for all of PciOr8(), PciAnd8() and PciRead8()):
PCI_LIB_ADDRESS (
PAM_PCI_BUS,
PAM_PCI_DEV,
PAM_PCI_FUNC,
mRegisterValues[Index].PAMRegOffset
)
-->
mRegisterValues[Index].PAMRegPciLibAddress
* Under CsmSupportLib, remove the PAM_PCI_* and REG_PAM*_OFFSET_* macros.
Technically speaking, these changes could be split into three patches
(IndustryStandard macro additions, CsmSupportLib code updates,
CsmSupportLib macro removals). However, the patch is not big, and in this
case it is actually helpful to present the code movement / refactoring in
one step, for easier verification.

Commit 8f0b62a5da ("BaseTools/tools_def AARCH64: enable frame pointers
for DEBUG builds") removed the -fomit-frame-pointer switch from the CFLAGS
definitions that are shared between AARCH64 DEBUG and RELEASE builds, and
moved it to the RELEASE specific ones, so that DEBUG builds can produce a
backtrace when a crash occurs.
This is actually a useful thing to have for RELEASE builds as well. AArch64
has 30 general purpose registers, and so the performance hit of having a
frame pointer is unlikely to be noticeable, nor are the additional 8 bytes
of stack space likely to present a problem.
So remove -fomit-frame-pointer altogether this time.

In UdfSetPosition(), the FID was retrieved through

PRIVATE_UDF_FILE_DATA.File.FileIdentifierDescriptor would be NULL and
then dereferenced.
This patch fixes the NULL pointer dereference by calling _FILE() to
