 Multicore is also supported by QEMU via '-smp n' where n is the number of cores
 to instantiate. Note, the maximum supported CPU number in QEMU is 255.
 
+U-Boot uses 'distro_bootcmd' by default when booting on x86 QEMU. This tries to
+load a boot script, kernel, and ramdisk from several different interfaces. For
+the default boot order, see 'qemu-x86.h'. For more information, see
+'README.distro'. Most Linux distros can be booted by writing a uboot script.
+For example, Debian (stretch) can be booted by creating a script file named
+'boot.txt' with the contents::
+
+   setenv bootargs root=/dev/sda1 ro
+   load ${devtype} ${devnum}:${distro_bootpart} ${kernel_addr_r} /vmlinuz
+   load ${devtype} ${devnum}:${distro_bootpart} ${ramdisk_addr_r} /initrd.img
+   zboot ${kernel_addr_r} - ${ramdisk_addr_r} ${filesize}
+
+Then compile and install it with::
+
+   $ apt install u-boot-tools && \
+     mkimage -T script -C none -n "Boot script" -d boot.txt /boot/boot.scr
+
 The fw_cfg interface in QEMU also provides information about kernel data,
 initrd, command-line arguments and more. U-Boot supports directly accessing
 these informtion from fw_cfg interface, which saves the time of loading them

+Slim Bootloader
+===============
+
+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
+
+The Slim Bootloader stages (Stage1A/B, Stage2) focus on chipset, hardware and
+platform specific initialization, and it provides useful information to a
+payload in a HOB (Hand-Off Block) which has serial port, memory map, performance
+data info and so on. This is Slim Bootloader architectural design to make a
+payload light-weight, platform independent and more generic across different
+boot solutions or payloads, and to minimize hardware re-initialization in a
+payload.
+
+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"
