Harry Liebel ef0fa8e16b ArmPkg: Remove BasePeCoffLib
ArmPkg contains unused and outdated code for runtime PE/COFF image
relocation.

- Use the version in MdePkg instead.
- Remove references to this package from BeagleBoardPkg.

ArmPkg/BasePeCoffLib was added to deal with MOVT instruction that
was not part of the PE/COFF specification at that time.

Olivier Martin 01674afdad ArmPkg/ArmLib: Drain Write Buffer before DCache maintenance operations.
Cache maintenance operations by Set/Way require that the Write Buffer
be drained before the cache is flushed.  Without that, the flush can
miss the most recent values written as they are still "pipelined".
That has unfortunate consequences, especially where code is being
copied to RAM.
The fix is to add DSB instructions before the affected operations.

Mark Salter 10ddca8db9 ArmPkg/BdsLib: Fix booting with partial paths
Boot entries created by efibootmgr may contain a partial device path
to the EFI application to boot. These entries begin with a partition
device path whereas entries created via ARM Boot Manager contain a
full path to the EFI application. The ARM BDS code will fill in the
missing parts of this partial device path as it does for removeable
device paths. This allows the application to be loaded and started.
However, the current code passes the original partial device path to
gBS->LoadImage() and thus LoadImage is unable to find a DeviceHandle
for the path. This means the application being booted cannot find the
boot device from the Loaded Image Protocol structure. In the case of
grub, this prevents the grub config file from being found. This patch
fixes this by making sure the full path is propagated back to the
caller of gBS->LoadImage() so that a proper DeviceHandle gets passed
to the application being booted.

oliviermartin aa4cf2ef96 ArmPkg/CpuDxe: Restore AArch64 system registers before returning from exception
Current EDK2 source code does actually trigger nested interrupted (even if
the PI spec says interrupt should not be nested).
This issue has highlighted the lack of restoring ELR_EL2/ELR_EL1 register.

Olivier Martin d8dc9f0af5 ArmPkg: Fixed GetEnvironmentVariable() when the UEFI Variable did not exist
The function was allocating a buffer for the read value from the UEFI Variable.
But it was returning the pointer of the default value when the variable was
not present.
It could cause error when the default value and the returned value were free
when these addresses were the same (double FreePool on the same address).

Olivier Martin 19dc108b65 ArmPkg/ArmLib: Correct Error Handling in AArch64
There are several instances of asserts which do not also handle
the error condition in Release builds.
Because these functions are called in different location of the
code and their parameters might change during the execution, it
is safer to handle the error.
