Subject: [PATCH] BaseTool: Support different PCDs to refer to the same EFI variable.
Date: Wed, 12 Sep 2018 14:10:36 +0800	[thread overview]
Message-ID: <20180912061036.11956-1-bob.c.feng@intel.com> (raw)

From: "bob.c.feng@intel.com" <bob.c.feng@intel.com>

If Structure PCD and Normal Pcd refer to the
same EFI variable, do EFI variable merge, otherwise, do
EFI variable combination.
