The BaseTools build feature introduced for TianoCore#1804 / in commit
1fa6699e6c ("BaseTools: Add a checking for Sources section in INF file",
2019-06-10) logs some (non-fatal) warnings about unlisted internal header
files. List those files explicitly.
Note: header files are added in lexicographical order only if the
underlying INF file already keeps the [Sources] and [LibraryClasses]
sections in lexicographical order. Otherwise, header files are added in
rough "logical" order.

The SP805 watchdog driver doesn't implement the PI watchdog protocol
fully, but always simply resets the system if the watchdog time runs
out.
However, the hardware does support the intended usage model, as long
as the SP805 is wired up correctly. So let's implement interrupt based
mode involving a handler that is registered by the DXE core and invoked
when the watchdog runs out. In the interrupt handler, we invoke the
notify function if one was registered, before calling the ResetSystem()
runtime service (as per the UEFI spec)

Currently, each flash bank controlled by ArmPlatformPkg/NorFlashDxe
has its own VendorHw GUID, and instances of NorFlashPlatformLib
describe each bank to the driver, along with the GUID for each.
This works ok for bare metal platforms, but it would be useful for
virtual platforms if we could obtain this information from a
device tree, which would require us to invent GUIDs on the fly,
given that the 'cfi-flash' binding does not include a GUID.
So instead, let's switch to a single GUID for all flash banks,
and update the driver's device path handling to include an index
to identify each bank uniquely.

The lazy initialization of the varstore FVB makes no longer sense at this
point:
- "mNorFlashInstanceTemplate.Initialize" is NULL;
- in NorFlashCreateInstance(), we only set Instance->Initialize to
non-NULL -- namely NorFlashFvbInitialize() -- if the FVB stands for the
variable store (see "ContainVariableStorage" / "SupportFvb");
- we call Instance->Initialize() from three places:
- from NorFlashWriteSingleBlock(), which is too late for the variable
read service ("variable write" depends on "variable read");
- from InitializeFvAndVariableStoreHeaders(), but that is only reachable
from NorFlashFvbInitialize(), i.e. recursively from
Instance->Initialize() itself;
- and from FvbRead(), which is never called by the variable driver, only
by the FTW driver. However, the variable driver may read (not write)
the memory-mapped varstore flash chip before the FTW driver is
dispatched.
Therefore the lazy initialization is both superfluous and insufficient.
Initialize the varstore headers eagerly, before we install the FVB
protocol interface.

The UEFI spec stipulates that unaligned accesses should be enabled
on CPUs that support them, which means all of them, given that we
no longer support pre-v7 ARM cores, and the AARCH64 bindings mandate
support for unaligned accesses unconditionally.
This means that one should not assume that CopyMem () is safe to call
on regions that may be mapped using device attributes, which is the
case for the NOR flash. Since we have no control over the mappings when
running under the OS, and given that write accesses require device
mappings, we should not call CopyMem () in the read path either, but
use our own implementation that is guaranteed to take alignment into

remove the mNorFlashVariableGuid global from the shared code and from both

The parameters are compared to the current state and no action taken if
