Subject: [`edk2-devel][PATCH v2] UefiPayloadPkg: Add ".upld_info" in universal
payload
From: Guo Dong <guo.d...@intel.com>
V2: Use LittleEndianStructure by review comment.
>From the universal scalable firmware payload requirement V0.75,
Payload must have Universal Payload Information Section ".upld_info"
So update the build tool to add this section.
