Olivier Martin 5d9e9d1a1c ArmPlatformPkg/Bds: Added support for booting legacy kernel from BDS
When PcdBdsLinuxSupport is enabled, users can create boot
entries for the legacy EFI Linux loader.

The ARM BDS detects if the image is a EFI image if not
then it assumes it is a legacy Linux kernel (a kernel
without EFI Stub).
If the Boot Manager did not manage to load the binary
(it could happen when the binary is on the network or
not present on the media yet).

Ard Biesheuvel 6cf1269d95 ArmPlatformPkg: enable use of authenticated variables in NorFlashDxe
The NorFlashDxe uses an explicit 'BEFORE xxx' Depex declaration to
ensure that it is dispatched before VariableRuntimeDxe, and uses the
file GUID of the latter as 'xxx' explicitly to accomplish that.

However, when enabling UEFI Secure Boot, this breaks down since the
authenticated VariableRuntimeDxe is a completely separate driver, with
a different GUID. Also, the hardcoded dependency on gEfiVariableGuid,
which is not used under UEFI Secure Boot, needs to be factored out in
order to allow this driver to be used.

So clone NorFlashDxe.inf into NorFlashAuthenticatedDxe.inf, and fix
up the dependencies so they refer to gEfiAuthenticatedVariableGuid and
SecurityPkg/VariableAuthenticated/RuntimeDxe/VariableRuntimeDxe.inf
instead.

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.

oliviermartin a6caee65ac ArmPlatformPkg: Remove PcdStandalone from Sec module and Introduce ArmPlatformSecExtraAction()
The PcdStandalone is a PCD ARM Ltd uses to make the difference between a standalone UEFI (boot
from cold boot to Boot Manager without user intervention) and a Debug UEFI firmware (the firmware
engineer has to copy the Normale World image into the DRAM to enable his/her firmware).

By coping the firmware into DRAM in the non standalone version it is much faster than reflashing
the NOR Flash after each build.

ArmPlatformSecExtraAction() function is called just before the Sec module jump to normal world.
The platform firmware can run extra actions at this stage.
The 'ARM Standalone' concept has moved to the implementation of ArmPlatformSecExtraAction() for
the ARM development boards (in ArmPlatformPkg/Library/DebugSecExtraActionLib).

The ArmPlatformLib was also declaring every region of its partitionned system memory
with a System Resource HOB.
    
In this new model, the MemoryInit expects the system memory to be declared with the
PCDs gArmTokenSpaceGuid.PcdSystemMemoryBase/Size.
These PCDs declare the largest continuous DRAM region. Additional regions can be
declared with the ArmPLatformLib function ArmPlatformGetAdditionalSystemMemory().
    
Now, it is the PEIM that partitions the system memory for every platform. It installs
a region of the size PcdSystemMemoryUefiRegionSize (default 128MB) for the PEI permanent
memory at the top of the DRAM region.
And a region of gArmPlatformTokenSpaceGuid.PcdSystemMemoryFixRegionSize (default 128MB)
is declared at the base of the system memory. This region is used for the allocation that
requires fixed address or have some constraints on their locations.
