From d0a0c52c221e5dcf82f24d4346c1cf52109d6dfb Mon Sep 17 00:00:00 2001 From: "Carsey, Jaben" Date: Sat, 28 Apr 2018 06:32:48 +0800 Subject: [PATCH] BaseTools: standardize GUID and pack size currently GUID packing and pack size determination is spread throughout the code. This introduces a shared function and dict and routes all code paths through them.
