Ard Biesheuvel c4cc609dc8 ArmPlatformPkg/PrePi: allow unicore version to be used on MP hardware
When combining UEFI firmware built from Tianocore with ARM Trusted
Firmware running in EL3, it is the responsibility of ATF that only
a single core enters the UEFI firmware in EL2, and the remaining cores
are released directly to the OS via PSCI SMC calls.

In this case, we don't need the MpCore flavor of PrePi or PrePeiCore,
but the UniCore flavor currently checks the CPU identification registers
directly, and refuses to proceed if the boot CPU is part of a MpCore
system.

So drop the ASSERT()'s that implement this check.

Leendert van Doorn 91673dfdfe ArmPlatformPkg: fixups for 64-bit pointers
This retypes some stack base PCD as 64-bit, and fixes up a number of references
to 64-bit PCDs (including the retypes ones), to use the correct PcdGet64()
accessors. Note that, in the case of FixedPcdGet64, this does not actually
caused any problems, since that resolves to an immediate value. But the
generic PcdGetxx accessors should be typed according to the size of the PCD.

Evan Lloyd fcea0fcb23 ArmPlatformPkg: Rectify file modes
Problems have been encountered because some of the source files have
execute permission set.  This can cause git to report them as changed
when they are checked out onto a file system with inherited permissions.
This has been seen using Cygwin, MinGW and PowerShell Git.

This patch makes no change to source file content, and only aims to
correct the file modes/permissions.

Olivier Martin 5dbacdb21b ArmPlatformPkg/PrePi: Make dynamic the top of the System Memory
This change allows to change the top of the System Memory that
was hardcoded by:
FixedPcdGet64 (PcdSystemMemoryBase) + FixedPcdGet64 (PcdSystemMemorySize)

It allows to add support when the Trusted Firmware reserves the
top of the System Memory as Trusted. The size of this region
might not be known in advance.

Note: The reason why the start of the System Memory has not been
made dynamic is because the early code calculates where to place
the stack from the top of the System Memory.
So there is no need to make the start of the System Memory a
dynamic value at the early stage of the boot phase.

This changes the definition and a bunch of references to
gArmTokenSpaceGuid.PcdSystemMemoryBase and
gArmTokenSpaceGuid.PcdSystemMemorySize so they can be declared as dynamic PCDs
by the platform. Also, move the non-SEC call to
ArmPlatformInitializeSystemMemory() earlier, so a platform has a chance to set
these PCDs before they are first referenced.

The purpose is allowing dynamically instantiated virtual machines to declare
the system memory by passing a device tree.

The stack size in the entrypoint (ie: $ARCH/ModuleEntryPoint.S) is calculated such as
StackSize = PrimaryCoreStack + (core_count - 1) * SecondaryCoreStack

While we were declaring the stacksize into the stack hob as:
StackSize = PrimaryCoreStack + (cluster * 8) * SecondaryCoreStack

If the number of cluster (ie: PcdClusterCount) were not defined correctly then
the stack size declaration were not correct.
It could cause stack corruption if the allocator allocates memory in this range.

oliviermartin b1d41be7c9 ArmPkg/ArmCpuLib: Replaced complex functions ArmCpuSynchronizeWait & ArmCpuSynchronizeSignal by sev & wfe
Previsouly the synchronization of MpCore was using the SGI (Software
Generated Interrupt) to synchronize MpCore during the early boot.
This commit replaced this mechanism by the more appropriate SEV/WFE
instructions (Send/Wait Event instructions).
That also eases the port to a new cpu/platform.

oliviermartin f437141a9c ArmPlatformPkg: Renamed and Invoked earlier ArmPlatformNormalInitialize()
- ArmPlatformNormalInitialize() has been renamed into ArmPlatformInitialize()
- Make the function be called at the early stage of the PEI phase as some
  platforms require their interconnects or clocks to be initialize before any
  access to Timers or UARTs.

oliviermartin 1377db63ff ArmPlatformPkg: Updated the stack setup to have the same geometry between the Secure and Normal World
Having a similar setup reduces the error during the MPCore stack setup.
The stack setup is described on this wikipage:

oliviermartin 2569b06868 ArmPlatformPkg/PrePi: Fixed stack setup when System Memory is mapped upto 0xFFFFFFFF
The stacks must be 32-bit aligned (which is not the case of 0xFFFFFFFF).
This change ensures the stacks are setup properperly in case the system
memory is available at 0xFFFFFFFF.
