vendorcode/intel: Add edk2-stable202005 support
This patch includes (edk2/edk2-stable202005) all required headers
for edk2-stable202005 quarterly EDK2 tag from EDK2 github project
using below command:
>> git clone https://github.com/tianocore/edk2.git vedk2-stable202005
Only include necessary header files.
MdePkg/Include/Base.h was updated to avoid compilation errors through
safeguarding definitions for MIN, MAX, NULL, ABS, ARRAY_SIZE.
