Laszlo Ersek 65ebe6e6c9 ArmVirtPkg/ArmVirtGicArchLib: eliminate unchecked PcdSetXX() calls
These are deprecated / disabled under the
DISABLE_NEW_DEPRECATED_INTERFACES feature test macro.

Introduce a variable called PcdStatus, and use it to assert the success of
these operations (there is no reason for them to fail here).

Dennis Chen 041e842ab7 ArmVirtPkg/ArmVirtGicArchLib: adapt ASSERT()s to 64-bit base addresses
Since All the GIC base address variables has been aligned to 64-bit, it
doesn't make sense to continue use MAX_UINT32 in ASSERT() statement, so
this patch uses MAX_UINTN to adapt to this kind of change.

Ard Biesheuvel cfc8d51c0c ArmVirtPkg/FdtClientDxe: report address and size cell count directly
The FDT client protocol methods dealing with "reg" properties return
the size of a "reg" element. Currently, we have hardcoded this as '8',
since #address-cells == #size-cells == 2 in most cases. However, for
different values, have a single 'reg' element size is not unambiguous,
since - however unlikely - if #address-cells != #size-cells, we do not
know which is which.

So before adding more methods to the protocol, fix up this oversight.

Dennis Chen 8a1f2378d7 ArmPkg ArmPlatformPkg ArmVirtPkg: ARM GICv2/v3 Base Address width fix-up
According to the ACPI 6.0/6.1 spec, the physical base address of GICC,
GICD, GICR and GIC ITS is 64-bit. So change the type of the various GIC
base address PCDs to 64-bit, and fix up all users.

Ard Biesheuvel 2248631883 ArmVirtPkg/ArmGicArchLib: move to FdtClient protocol
Instead of relying on VirtFdtDxe to populate the GIC related PCDs, move
this handling to our implementation of ArmGicArchLib, and retrieve the
required DT info using the new FDT client protocol.

This removes one of the reasons we need to load VirtFdtDxe first using
an 'A PRIORI' declaration in the platform FDF.

As Laszlo kindly confirms:

  So, ultimately, the only user of this library instance is
  "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf". ... Indeed, checking the build
  report file for ArmVirtQemu (AARCH64), I find ArmVirtGicArchLib (and
  ArmGicLib too) only under "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf".

which means that the constructor is only invoked once, and so the dynamic
PCDs are set in time for ArmGicDxe to consume them, and never afterwards.

Ard Biesheuvel 15c9b25e5d ArmVirtPkg: implement DT-based ArmGicArchLib
Since it is arguably incorrect to infer the GIC revision from CPU
ID and GIC feature registers on platforms that describe the GIC in
the device tree, this implements the library class ArmGicArchLib
tailored for such platforms.

The supported GIC revision is retrieved from the dynamic PCD that
is set based on the GIC DT node.

This means this library can only execute post DXE core, but this is
not a problem for any of the virt platforms.
