From 6d27778973edf6bdebfa812eac8893d52961a891 Mon Sep 17 00:00:00 2001 From: Jonathan Zhang Date: Tue, 9 Jun 2020 17:56:53 -0700 Subject: 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.
