+Introduction
+============
+This target is to enable U-Boot as a payload of Slim Bootloader(a.k.a SBL)
+boot firmware(https://github.com/slimbootloader) which currently supports
+QEMU, Apollolake, Whiskeylake, Coffeelake-R platforms.
+
+The Slim Bootloader is designed with multi-stages(Stage1A/B, Stage2, Payload)
+architecture to cover from reset vector to OS booting and it consumes Intel FSP
+(https://github.com/IntelFsp) for silicon initialization.
+* Stage1A: Reset vector, CAR init with FSP-T
+* Stage1B: Memory init with FSP-M, CAR teardown, Continue execution in memory
+* Stage2 : Rest of Silicon init with FSP-S, Create HOB, Hand-off to Payload
+* Payload: Payload init with HOB, Load OS from media, Booting OS
+
+
+
+Here is the step-by-step to launch U-Boot on Slim Bootloader.
+
+Compile U-Boot
+==============
+
+ > make distclean
+ > make slimbootloader_defconfig
+ > make all
+
+
+
+Prepare Slim Bootloader with u-boot-dtb.bin
+===================================================
+
+For build environment:
+ https://slimbootloader.github.io/getting-started
+
+Get source code:
+ > git clone https://github.com/slimbootloader/slimbootloader.git
+
+Copy the built u-boot-dtb.bin to Slim Bootloader source tree:
+ > mkdir -p <slimbootloader_home>/PayloadPkg/PayloadBins/
+ > cp <u-boot_home>/u-boot-dtb.bin <slimbootloader_home>/PayloadPkg/PayloadBins/u-boot-dtb.bin
+
+
+
+Compile Slim Bootloader with U-Boot for QEMU target
+===================================================
+
+Update default payload to U-Boot (PayloadId is 4 Bytes):
+ Any 4 Bytes PayloadId is okay, but use 'U-BT' as an example.
+ > vi Platform/QemuBoardPkg/CfgData/CfgDataExt_Brd1.dlt
+ -GEN_CFG_DATA.PayloadId | 'AUTO'
+ +GEN_CFG_DATA.PayloadId | 'U-BT'
+
+Update payload text base in QEMU BoardConfig.py:
+ PAYLOAD_EXE_BASE must be the same as u-boot text base in board/intel/slimbootloader/Kconfig.
+ PAYLOAD_LOAD_HIGH must be 0.
+ > vi Platform/QemuBoardPkg/BoardConfig.py
+ + self.PAYLOAD_LOAD_HIGH = 0
+ + self.PAYLOAD_EXE_BASE = 0x00100000
+
+Compile for QEMU target:
+ Make sure u-boot-dtb.bin and U-BT PayloadId in build command.
+ > python BuildLoader.py build qemu -p "OsLoader.efi:LLDR:Lz4;u-boot-dtb.bin:U-BT:Lzma"
+ The output is Outputs/qemu/SlimBootloader.bin
+
+Launch Slim Bootloader on QEMU:
+ > qemu-system-x86_64 -machine q35 -m 256 -nographic -serial mon:stdio
+ -pflash Outputs/qemu/SlimBootloader.bin
+ Now, you should reach at U-Boot serial console.
+
+
+
+Compile Slim Bootloader with U-Boot for LeafHill(APL) target
+============================================================
+
+Compile U-Boot with CONFIG_SYS_NS16550_MEM32:
+ LeafHill has PCI UART2 MMIO32 serial port. Set CONFIG_SYS_NS16550_MEM32.
+ > vi include/configs/slimbootloader.h
+ +#define CONFIG_SYS_NS16550_MEM32
+ #ifdef CONFIG_SYS_NS16550_MEM3
+ > make disclean
+ > make slimbootloader_defconfig
+ > make all
+
+Copy the built u-boot-dtb.bin to Slim Bootloader source tree:
+ > mkdir -p <slimbootloader_home>/PayloadPkg/PayloadBins/
+ > cp <u-boot_home>/u-boot-dtb.bin <slimbootloader_home>/PayloadPkg/PayloadBins/u-boot-dtb.bin
+
+Update default payload to U-Boot (PayloadId is 4 Bytes):
+ Any 4 Bytes PayloadId is okay, but use 'U-BT' as an example.
+ > vi Platform/ApollolakeBoardPkg/CfgData/CfgData_Int_LeafHill.dlt
+ -GEN_CFG_DATA.PayloadId | 'AUTO'
+ +GEN_CFG_DATA.PayloadId | 'U-BT'
+
+Update payload text base in APL BoardConfig.py:
+ PAYLOAD_EXE_BASE must be the same as u-boot text base in board/intel/slimbootloader/Kconfig.
+ PAYLOAD_LOAD_HIGH must be 0.
+ > vi Platform/ApollolakeBoardPkg/BoardConfig.py
+ + self.PAYLOAD_LOAD_HIGH = 0
+ + self.PAYLOAD_EXE_BASE = 0x00100000
+
+Compile for APL target:
+ Make sure u-boot-dtb.bin and U-BT PayloadId in build command.
+ > python BuildLoader.py build apl -p "OsLoader.efi:LLDR:Lz4;u-boot-dtb.bin:U-BT:Lzma"
+ The output is Outputs/apl/Stitch_Components.zip
+
+Stitch IFWI:
+ Refer to https://slimbootloader.github.io/supported-hardware/apollo-lake-crb.html#stitching.
+ > python Platform/ApollolakeBoardPkg/Script/StitchLoader.py -i <Existing IFWI> -s Outputs/apl/Stitch_Components.zip -o <Output IFWI>
+
+Flash IFWI:
+ Use DediProg to flash IFWI.
+ Now, you should reach at U-Boot serial console.
+
+
+
+To use ELF U-Boot
+=================
+
+Compile U-Boot with CONFIG_OF_EMBED:
+ > vi configs/slimbootloader_defconfig
+ +CONFIG_OF_EMBED=y
+ > make distclean
+ > make slimbootloader_defconfig
+ > make all
+ > strip u-boot (To reduce image size by removing symbol)
+
+Do the same steps as above:
+ Copy u-boot to PayloadBins directory
+ Use u-boot in build command instead of u-boot-dtb.bin
+ No need to set PAYLOAD_LOAD_HIGH and PAYLOAD_EXE_BASE
