Subject: [PATCH] IntelFsp2WrapperPkg: Support UPD allocation outside FspWrapper
Date: Thu, 23 Nov 2017 10:30:03 +0800 [thread overview]
Message-ID: <20171123023003.10552-1-chasel.chiu@intel.com> (raw)
UPD allocation and patching can be done outside FspWrapper
as implementation choice so adding a PCD to select between
original FspWrapper allocation model or outside model
