From cd3692b11ed3c760acc1015ac19785b9a36054e8 Mon Sep 17 00:00:00 2001 From: Satya Yarlagadda Date: Sat, 17 Sep 2016 11:24:49 +0800 Subject: IntelFsp2Pkg: Align #Pragma in UPD header files to rest of EDK2 Pkgs Changed the GenCfgOpt.py script to insert pragma pack(1) instead of pragma pack (push, 1) in the upd header files generated during fsp build. This is to align with rest of the EDKII pkgs pragma pack usage. Also, this scripts generates UnusedUpdSpace for UPD address gaps. Currently it uses UIN16/UINT32/UINT64 for 2/4/8 bytes instead of UINT8[], thus causing upd space waste to have Natural Alignment. Hence changed the script to use UINT8[] for any unusedUpd fields above 1 byte.
