> FdfParser.py has defined a key named OEM_CAPSULE_FLAGS to set the
> lower 16 bits of EFI_CAPSULE_HEADER.Flags. However, this key is totally
> "forgotten" in Capsule.py, making it impossible to set lower 16 bits of
> this field, and leading to an always FALSE when comparing to
> gEfiMdeModulePkgTokenSpaceGuid.PcdSystemRebootAfterCapsuleProcessFla
> g
> in MdeModulePkg/Library/DxeCapsuleLibFmp/DxeCapsuleProcessLib.c:
> ProcessTheseCapsules().
> 
> This patch ORs the value of OEM_CAPSULE_FLAGS with previously calculated
> CAPSULE_FLAGS value, making the lower 16 bits of value being correctly
set.
