[edk2-devel] [PATCH V2 0/1] UefiPayloadPkg: Remove PEI phase from Payload

["Guo Dong" <guo.dong@intel.com>]

Hi All,

This patch removed UEFI payload PEI phase to make UEFI payload simple.
It uses UefiPayloadEntry module to bridge bootloader and DXE phase.

Original DSC files UefiPayloadIa32.dsc and UefiPayloadIa32X64.dsc
are replaced by a single DSC UefiPayloadPkg.dsc. Pure IA32 support
is replaced by Pure X64 support. IA32 Entry point with X64 DXE phase
is still supported.

Changes in V2:
Addressed all the review comments from Maurice.
Fixed debug msg in UefiPayloadEntry. 
Updated the Handoff HOB to DXE core to include Payload FV.
Synced the GHCB changes from DxeIpl to UefiPayloadEntry.

V1: 
It is not necessary to have a PEI phase in the UEFI payload since no
specific PEI task is required. This patch adds a UefiPayloadEntry
driver to get UEFI Payload required information from the bootloaders,
convert them into a HOB list, load DXE core and transfer control to it.

Here is the change details:
1) Removed PEI phase, including Peicore, BlSupportPei, SecCore, etc.
2) Added UefiPayloadEntry driver. this is the only driver before DXE core.
3) Added Pure X64 support, dropped Pure IA32 (Could add later if required)
   64bit payload with 32bit entry point is still supported.
4) Use one DSC file UefiPayloadPkg.dsc to support X64 and IA32X64 build.
   Removed UefiPayloadIa32.dsc and UefiPayloadIa32X64.dsc

Tested with SBL and coreboot on QEMU.
