The format specifier for the LoadOptions field of the LoadedImage protocol
is "%s". However, the data in LoadOptions is often generic binary data. A
format specifier of "%x" is more appropriate for this field.
Using "dh -v" with format specifier "%s" on BIOS images based on EDK II
source before commit 891d844 can cause a crash.

The original logic assumes GOP hande is son of PCI handle but it
is not always true.
Below wordings are from UEFI Spec:
If a graphics device supports multiple frame buffers, then
handles for the frame buffers must be created first, and then the
handles for the video output devices can be created as children of
the frame buffer handles.
So the GOP handle could be grandson of the PCI handle.
EfiBootManagerGetGopDevicePath(VideoController) is used to fix
this bug.

Current PI spec has no clear description about whether the

If the SkuId could be changed multiple times during one boot,
different modules may get inconsistent PCD values.
And DynamicHii PCD maps to UEFI variable, once one DynamicHii
PCD(UEFI variable) is set for one SkuId, then the PCD value
will be always from UEFI variable but not PCD database, even
the SkuId is set to other value.
This patch is to update PCD drivers to allow SkuId to be

Commit e7b24ec978 ("ArmPkg/UncachedMemoryAllocationLib: map uncached
allocations non-executable") adds code that manipulates the GCD memory
space attributes of a newly allocated uncached region without checking
whether this region expose these attributes in its capabilities mask.
Given that the intent is to remove executable permissions from the region,
this is a fairly pointless exercise to begin with, regardless of whether
it is correct or not. The reason is that RO/XP memory attributes in the
GCD memory space map or the UEFI memory map are completely disconnected
from the actual mapping permissions used in the page tables.
So instead, invoke the CPU arch protocol directly, and add the non-exec
attributes in the page tables directly.

We cannot entirely eliminate the manual boot script building in this
driver, as it also programs lower-level chipset registers (SMI_EN,
GEN_PMCON_1) at S3 resume, not just registers exposed via fw_cfg.
We can nonetheless replace the manually built opcodes for the latter class
of registers with QemuFwCfgS3Lib function calls. We preserve the ordering
between the two sets of registers (low-level chipset first, fw_cfg
second).
This patch demonstrates that manual handling of S3SaveState protocol
installation can be combined with QemuFwCfgS3Lib, even without upsetting
the original order between boot script fragments. An S3SaveState notify
function running at TPL_CALLBACK can safely queue another S3SaveState
notify function at TPL_CALLBACK with QemuFwCfgS3CallWhenBootScriptReady().

In the DXE fw_cfg instance:
- QemuFwCfgS3Enabled() queries S3 enablement via fw_cfg. This behavior is
shared with the PEI fw_cfg instance, and the DXE fw_cfg instance already
pulls in the function from "QemuFwCfgS3PeiDxe.c".
- If QemuFwCfgS3Enabled() returns TRUE, the client module is permitted to
call QemuFwCfgS3CallWhenBootScriptReady().
We provide a fully functional implementation for
QemuFwCfgS3CallWhenBootScriptReady(). A protocol notify is installed at
TPL_CALLBACK for EFI_S3_SAVE_STATE_PROTOCOL. If / once the protocol is
available, the client module's Callback() function is called, which is
expected to produce ACPI S3 Boot Script opcodes using the helper
functions listed below. In QemuFwCfgS3CallWhenBootScriptReady(), we also
allocate a reserved memory buffer, sized & typed by the client module,
for the opcodes and (internally) the fw_cfg DMA operations to work upon,
during S3 resume.
This behavior is unique to the DXE fw_cfg instance. Thus, add the
function to "QemuFwCfgS3Dxe.c".
- The QemuFwCfgS3ScriptWriteBytes(), QemuFwCfgS3ScriptReadBytes(),
QemuFwCfgS3ScriptSkipBytes(), and QemuFwCfgS3ScriptCheckValue()
functions are also implemented usefully, since the client module's
Callback() function is expected to invoke them.
Each of the first three functions produces MEM_WRITE, IO_WRITE, and
MEM_POLL opcodes, to set up the DMA command in reserved memory, to start
the DMA transfer, and to check the DMA result, respectively.
The QemuFwCfgS3ScriptCheckValue() function produces a MEM_POLL opcode to
validate an unsigned integer field in data that was read via
QemuFwCfgS3ScriptReadBytes().
This behavior is again unique to the DXE fw_cfg instance, so add the
functions to "QemuFwCfgS3Dxe.c".
