commit f13264b34 introduces a bug for CloudHv as OvmfPkg/OvmfPkg.dec is
missing in CloudHvHasAcpiDtDxe.inf which leads to
gUefiOvmfPkgTokenSpaceGuid found nowhere when build.

The BIOS Firmware Version in the SMBIOS Type 0 can be fetched from
the fixed PcdFirmwareVersionString or platform specific OemMiscLib.
In fact, the support from OemMiscLib comes into play when the firmware
version may be modified at boot time for extended information.
Therefore, the priority of getting the version from OemMiscLib should
be higher.
In case there is no modification in the OemMiscLib, we have to keep
HII string STR_MISC_BIOS_VERSION empty or 'Not Specified'
to indicate that the firmware version should be fetched from
the PcdFirmwareVersionString.

Also swap the ordering of 32bit PCI MMIO window on q35, i.e. use the
room between end of low memory and the start of the mmconfig bar.
With a typical configuration on modern qemu with gigabyte-aligned memory
the MMIO window start at 0x8000000, sized 1532 MB. In case there is
memory present above 0x80000000 the window will start at 0xc0000000
instead, with 512 MB size.
This depends on qemu commit 4a4418369d6d ("q35: fix mmconfig and

to qemu 4.1 (released Aug 2019).

M-mode firmware ranges should not be used by EDK2/OS.
Currently, we search for mmode_resv0 node in FDT and mark it as the
reserved memory in EFI memory map. However, if there are multiple
M-mode firmware ranges, then this will miss those extra ranges
allowing the OS to access the memory and hit a fault.
This issue is exposed since recent opensbi started creating
two ranges for text and data.
Fix this by searching for all reserved memory nodes and marking
them as reserved in the EFI memory map.

Modify CpuPageTableLib code to enable PAE paging.
In PageTableMap() API:
When creating new PAE page table, after creating page table,
set all MustBeZero fields of 4 PDPTE to 0. The MustBeZero
fields are treated as RW and other attributes by the common
map logic. So they might be set to 1.
When updating exsiting PAE page table, the special steps are:
1.Prepare 4K-aligned 32bytes memory in stack for 4 temp PDPTE.
2.Copy original 4 PDPTE to the 4 temp PDPTE and set the RW,
UserSupervisor to 1 and set Nx of 4 temp PDPTE to 0.
4.After updating the page table, set the MustBeZero fields of
4 temp PDPTE to 0.
5.Copy the temp PDPTE to original PDPTE.
In PageTableParse() API, also create 4 temp PDPTE in stack.
Copy original 4 PDPTE to the 4 temp PDPTE. Then set the RW,
UserSupervisor to 1 and set Nx of 4 temp PDPTE to 0. Finally
use the address of temp PDPTE as the page table address.

Add code to compare ParentPagingEntry Attribute&Mask and input
Attribute&Mask to decide if new next level page table is needed
in non-present ParentPagingEntry condition. This can help avoid
unneccessary page table creation.
For example, there is a page table in which [0, 1G] is mapped(Lv4[0]
,Lv3[0,0], a non-leaf level4 entry and a leaf level3 entry).And we
only want to map [1G, 1G+2M] linear address still as non-present.
The expected behaviour should be nothing happens in the process.
However, previous code logic doesn't check if ParentPagingEntry
Attribute&Mask and input Attribute&Mask are the same in non-present
ParentPagingEntry condition. Then a new 4K memory is allocated for
Lv2 since 1G+2M is not 1G-aligned.
So when ParentPagingEntry is non-present, before allocate 4K memory
for next level paging, we also check if ParentPagingEntry Attribute&
Mask and input Attribute&Mask are the same.

In previous code logic, when splitting a leaf parent entry to
smaller granularity child page table, if the parent entry
Attribute&Mask(without PageTableBaseAddress field) is equal to the
input attribute&mask(without PageTableBaseAddress field), the split
process won't happen. This may lead to failure in non-1:1 mapping.
For example, there is a page table in which [0, 1G] is mapped(Lv4[0]
,Lv3[0,0], a non-leaf level4 entry and a leaf level3 entry). And we
want to remap [0, 2M] linear address range to [1G, 1G + 2M] with the
same attibute. The expected behaviour should be: split Lv3[0,0]
entry into 512 level2 entries and remap the first level2 entry to
cover [0, 2M]. But the split won't happen in previous code since
PageTableBaseAddress of input Attribute is not checked.
So, when checking if a leaf parent entry needs to be splitted, we
should also check if PageTableBaseAddress calculated by parent entry
is equal to the value caculated by input attribute.
