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 f2e17a0731 ArmPlatformPkg/PrePi: remove global variable allocation from lowlevel init
Now that we dropped all ArmPlatformGlobalVariableLib dependencies,
there is no longer a need to allocate and clear out the global
variable region in the PrePi init code. So remove it.

Olivier Martin 1b0ac0dedf ArmPkg/ArmGic: Returned the InterruptId in ArmGicAcknowledgeInterrupt()
The InterruptId has a different width for GicV2 and GicV3 (respectively
10bit and 24bit).
The function prototype has been changed to return this value to make the
caller GIC architecture version independent. Otherwise, we would have need
to expose a different mask to allow the caller to retrieve this value from
the read register.

Olivier Martin f93f248a78 ArmPlatformPkg: Removed the check on the CpuId to release the secondary cores from their mailbox spinning
The idea is to remove the PCD PcdGicPrimaryCoreId to make the port easier (and also to allow changing
the primary boot CPU without adding more platform specific code to UEFI).

There is a risk the mailboxes contain garbage at boot time. But it should be easy enough to clear the
mailboxes when starting UEFI to workaround this limitation.

oliviermartin 0787bc6184 ArmPlatformPkg: Introduce Primary core macros
On MpCore system, the primary core can now be any core of the system.

To identify the primary core, you can use 'gArmTokenSpaceGuid.PcdArmPrimaryCoreMask'
and 'gArmTokenSpaceGuid.PcdArmPrimaryCore'.
These PCDs by default use the ClusterId and CoreId to identify the core. And the
primary core is defined as the ClusetrId=0 and CoreId=0.

The helper macros are: IS_PRIMARY_CORE(MpId), GET_CORE_ID(MpId), GET_CLUSTER_ID(MpId),
GET_CORE_POS(MpId), PRIMARY_CORE_ID.

oliviermartin d269095b71 ArmPlatformPkg: Change the memory model for the ARM Platform components
In the former memory model, the UEFI firmware was expected to be located
at the top of the system memory. Stacks & Pi memory regions were set below
the firmware.
On some platform, the UEFI firmware could be shadowed by the ROM firmware
(case of the BeagleBoard) and in some cases the firmware is copied at the
beginning of the system memory.

With this new memory model, stack and Pi/DXE memory regions are set at the
top of the system memory wherever the UEFI firmware is located in the memory
map.
Because DXE core does not support shadowed firmwares, the system memory covered
by the UEFI firmware is marked as 'Non Present' to avoid to be overlapped by
DXE allocations.
