+U-Boot as a Slim Bootloader payload
+===================================
+
+Introduction
+------------
+
+This target is to enable U-Boot_ as a payload of `Slim Bootloader`_ (a.k.a SBL)
+boot firmware 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`_ 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
+
+Build Instruction for U-Boot as a Slim Bootloader payload
+---------------------------------------------------------
+
+Build U-Boot and obtain u-boot-dtb.bin::
+
+   $ make distclean
+   $ make slimbootloader_defconfig
+   $ make all
+
+Prepare Slim Bootloader
+-----------------------
+
+1. Setup Build Environment for Slim Bootloader.
+
+   Refer to `Getting Started`_ page in `Slim Bootloader`_ document site.
+
+2. Get source code. Let's simply clone the repo::
+
+   $ git clone https://github.com/slimbootloader/slimbootloader.git
+
+3. Copy u-boot-dtb.bin to Slim Bootloader.
+   Slim Bootloader looks for a payload from the specific location.
+   Copy the build u-boot-dtb.bin to the expected location::
+
+   $ mkdir -p <Slim Bootloader Dir>/PayloadPkg/PayloadBins/
+   $ cp <U-Boot Dir>/u-boot-dtb.bin <Slim Bootloader Dir>/PayloadPkg/PayloadBins/u-boot-dtb.bin
+
+Build Instruction for Slim Bootloader for QEMU target
+-----------------------------------------------------
+
+Slim Bootloader supports multiple payloads, and a board of Slim Bootloader
+detects its target payload by PayloadId in board configuration.
+The PayloadId can be any 4 Bytes value.
+
+1. Update PayloadId. Let's use 'U-BT' as an example::
+
+    $ vi Platform/QemuBoardPkg/CfgData/CfgDataExt_Brd1.dlt
+    -GEN_CFG_DATA.PayloadId                     | 'AUTO'
+    +GEN_CFG_DATA.PayloadId                     | 'U-BT'
+
+2. Update payload text base. PAYLOAD_EXE_BASE must be the same as U-Boot
+   CONFIG_SYS_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
+
+3. Build QEMU target. Make sure u-boot-dtb.bin and U-BT PayloadId
+   in build command. The output is Outputs/qemu/SlimBootloader.bin::
+
+   $ python BuildLoader.py build qemu -p "OsLoader.efi:LLDR:Lz4;u-boot-dtb.bin:U-BT:Lzma"
+
+4. Launch Slim Bootloader on QEMU.
+   You should reach at U-Boot serial console::
+
+   $ qemu-system-x86_64 -machine q35 -nographic -serial mon:stdio -pflash Outputs/qemu/SlimBootloader.bin
+
+Build Instruction for Slim Bootloader for LeafHill(APL) target
+--------------------------------------------------------------
+
+LeafHill is using PCI UART2 device as a serial port.
+For MEM32 serial port, CONFIG_SYS_NS16550_MEM32 needs to be enabled in U-Boot.
+
+1. Enable CONFIG_SYS_NS16550_MEM32 in U-Boot::
+
+    $ vi include/configs/slimbootloader.h
+    +#define CONFIG_SYS_NS16550_MEM32
+     #ifdef CONFIG_SYS_NS16550_MEM3
+
+2. Build U-Boot::
+
+   $ make disclean
+   $ make slimbootloader_defconfig
+   $ make all
+
+3. Copy u-boot-dtb.bin to Slim Bootloader.
+   Slim Bootloader looks for a payload from the specific location.
+   Copy the build u-boot-dtb.bin to the expected location::
+
+   $ mkdir -p <Slim Bootloader Dir>/PayloadPkg/PayloadBins/
+   $ cp <U-Boot Dir>/u-boot-dtb.bin <Slim Bootloader Dir>/PayloadPkg/PayloadBins/u-boot-dtb.bin
+
+4. Update PayloadId. Let's 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'
+
+5. Update payload text base.
+
+* PAYLOAD_EXE_BASE must be the same as U-Boot CONFIG_SYS_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
+
+6. Build APL target. Make sure u-boot-dtb.bin and U-BT PayloadId
+   in build command. The output is Outputs/apl/Stitch_Components.zip::
+
+   $ python BuildLoader.py build apl -p "OsLoader.efi:LLDR:Lz4;u-boot-dtb.bin:U-BT:Lzma"
+
+7. Stitch IFWI.
+
+   Refer to Apollolake_ page in Slim Bootloader document site::
+
+   $ python Platform/ApollolakeBoardPkg/Script/StitchLoader.py -i <Existing IFWI> -s Outputs/apl/Stitch_Components.zip -o <Output IFWI>
+
+8. Flash IFWI.
+
+   Use DediProg to flash IFWI. You should reach at U-Boot serial console.
+
+
+Build Instruction to use ELF U-Boot
+-----------------------------------
+
+1. Enable CONFIG_OF_EMBED::
+
+    $ vi configs/slimbootloader_defconfig
+    +CONFIG_OF_EMBED=y
+
+2. Build U-Boot::
+
+   $ make disclean
+   $ make slimbootloader_defconfig
+   $ make all
+   $ strip u-boot (removing symbol for reduced size)
+
+3. Do same steps as above
+
+* Copy u-boot(ELF) to PayloadBins directory
+* Update PayloadId 'U-BT' as above.
+* No need to set PAYLOAD_LOAD_HIGH and PAYLOAD_EXE_BASE.
+* Build Slim Bootloader. Use u-boot instead of u-boot-dtb.bin::
+
+   $ python BuildLoader.py build <qemu or apl> -p "OsLoader.efi:LLDR:Lz4;u-boot:U-BT:Lzma"
