Subject: [PATCH] UefiPayloadPkg: Use DynamicEx instead of Dynamic to pass PCD across binary
Date: Wed, 2 Jun 2021 22:39:03 +0800 [thread overview]
Message-ID: <20210602143903.1587-1-zhiguang.liu@intel.com> (raw)
When passing PCD database from Edk2 boot loader to Universal Payload, the local
token number in boot loader PCD database can be different with that in Payload
PCD database.
Dynamic PCD directly use local token number, while DynamicEx will search token number
by Guid and ExTokenNumber, which are unique pair and can make sure finding the correct
token number in boot loader's PCD database
