[PATCH v2 edk2-platforms 0/3] Platform/ARM: fix DevicePath mishandling in BdsLib

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

The deprecated BdsLib library class in ArmPkg is still depended upon, but
only a single implementation exists, which now resides in edk2-platforms.

This implementation has some issues in how it deals with Device Paths,
so let's fix those, but first move over the library interface declaration
and get rid of the parts that are no longer used. This will permit dropping
it from ArmPkg in EDK2.

Changes since v1:
- add Laszlo's ack to #1
- update #2 to remove everything we no longer need from BdsLib
- drop #3 which was bogus
- update #4 to ensure that we only duplicate the device path when we
  are about to return EFI_SUCCESS

Ard Biesheuvel (3):
  Platform/ARM: import ARM platform specific BdsLib header
  Platform/ARM/BdsLib: drop unused functions
  Platform/ARM/BdsLib: maintain alignment for DevicePaths
