A. INTRODUCTION
================================================================================
This document provides instructions on how to build UEFI Payload and how to
integrate it into coreboot or Slim Bootloader firmware.

================================================================================
B. HOW TO BUILD
================================================================================
1. Run the below two commands in windows command prompt window:
   edksetup.bat

   For debug ia32 build:
   build -a IA32 -p UefiPayloadPkg\UefiPayloadPkgIa32.dsc -b DEBUG -t <ToolChain> -D BOOTLOADER=<Bootloader>

   For release ia32 build:
   build -a IA32 -p UefiPayloadPkg\UefiPayloadPkgIa32.dsc -b RELEASE -t <ToolChain> -D BOOTLOADER=<Bootloader>

   For debug X64 build:
   build -a IA32 -a X64 -p UefiPayloadPkg\UefiPayloadPkgIa32X64.dsc -b DEBUG -t <ToolChain> -D BOOTLOADER=<Bootloader>

   For release X64 build:
   build -a IA32 -a X64 -p UefiPayloadPkg\UefiPayloadPkgIa32X64.dsc -b RELEASE -t <ToolChain> -D BOOTLOADER=<Bootloader>

   <ToolChain> is the EDK II build environment on your host. Currently it was tested
   with VS2015x86 toolchain.
   <Bootloader> could be "SBL" for Slim Bootloader and "COREBOOT" for coreboot.

   Refer to https://github.com/tianocore/tianocore.github.io/wiki/UDK2018-How-to-Build for
   details about EDK II build steps.

2. If build is successfully, the payload image (UEFIPAYLOAD.fd) will be generated inside the
   folder of Build\UefiPayloadPkg.

================================================================================
C. HOW TO INTEGRATE INTO COREBOOT
================================================================================
1. Copy the payload image (UEFIPAYLOAD.fd) into the top-level directory of Coreboot source tree.
2. Run "make menuconfig" in linux console to start Coreboot configuration surface.
3. In the Payload section,
   1) Choose "An ELF executable payload" for the option of "Add a payload".
   2) Type the path of payload image for the option of "Payload path and filename".
   3) Select the option of "Use LZMA compression for payloads".
4. If the graphics console is required in UEFI payload, enable framebuffer initialization in coreboot.
   This could be done by enabling native graphics or using VGA BIOS option rom.
5. Build the coreboot firmware image.

================================================================================
D. HOW TO INTEGRATE INTO SLIM BOOTLOADER
================================================================================
Please refer https://slimbootloader.github.io/how-tos/integrate-multiple-payloads.html for below steps.
1. Copy the payload image (UEFIPAYLOAD.fd) into Slim Bootloader source at PayloadPkg\PayloadBins\UefiPld.fd
2. Update config data to make UEFI payload as default payload if required.
3. Build Slim Bootloader with UEFI payload:
   BuildLoader.py build <Platform> -p "OsLoader.efi:LLDR:Lz4;UefiPld.fd:UEFI:Lzma"
