+StarFive VisionFive2
+====================
+
+JH7110 RISC-V SoC
+---------------------
+The JH7110 is 4+1 64-bit RISC-V SoC from StarFive.
+
+The StarFive VisionFive2 development platform is based on JH7110 and capable
+of running Linux.
+
+Mainline support
+----------------
+
+The support for following drivers are already enabled:
+
+1. ns16550 UART Driver.
+2. StarFive JH7110 clock Driver.
+3. StarFive JH7110 reset Driver.
+4. Cadence QSPI controller Driver.
+5. MMC SPI Driver for MMC/SD support.
+
+Booting from MMC using U-Boot SPL
+---------------------------------
+
+The current U-Boot port is supported in S-mode only and loaded from DRAM.
+
+A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
+boot the u-boot.itb in S-mode and provide M-mode runtime services.
+
+Currently, the u-boot.itb is used as a dynamic of the OpenSBI FW_DYNAMIC
+firmware with the latest.
+
+Building
+~~~~~~~~
+
+1. Add the RISC-V toolchain to your PATH.
+2. Setup ARCH & cross compilation environment variable:
+
+.. code-block:: none
+
+ export CROSS_COMPILE=<riscv64 toolchain prefix>
+
+Before building U-Boot SPL, OpenSBI must be built first. OpenSBI can be
+cloned and built for JH7110 as below:
+
+.. code-block:: console
+
+ git clone https://github.com/riscv/opensbi.git
+ cd opensbi
+ make PLATFORM=generic FW_TEXT_START=0x40000000 FW_OPTIONS=0
+
+More detailed description of steps required to build FW_DYNAMIC firmware
+is beyond the scope of this document. Please refer OpenSBI documenation.
+(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
+
+Now build the U-Boot SPL and U-Boot proper
+
+.. code-block:: console
+
+ cd <U-Boot-dir>
+ make starfive_visionfive2_13b_defconfig
+ make OPENSBI=$(opensbi_dir)/opensbi/build/platform/generic/firmware/fw_dynamic.bin
+
+This will generate spl/u-boot-spl.bin and FIT image (u-boot.itb)
+
+u-boot-spl.bin cannot be used directly on StarFive VisionFive2,we need
+to convert the u-boot-spl.bin to u-boot-spl.bin.normal.out with
+the below command:
+
+ ./spl_tool -c -f $(Uboot_PATH)/spl/u-boot-spl.bin
+
+More detailed description of spl_tool,please refer spl_tool documenation.
+(Note: spl_tool git repo is at https://github.com/starfive-tech/Tools/tree/master/spl_tool)
+
+This will generate u-boot-spl.bin.normal.out file.
+
+Flashing
+~~~~~~~~
+
+SPL loads the U-Boot SPL (u-boot-spl.bin.normal.out) from a partition with GUID type
+2E54B353-1271-4842-806F-E436D6AF6985
+
+U-Boot SPL expects a U-Boot FIT image (u-boot.itb) from a partition with GUID
+type BC13C2FF-59E6-4262-A352-B275FD6F7172
+
+FIT image (u-boot.itb) is a combination of fw_dynamic.bin, u-boot-nodtb.bin and
+device tree blob (jh7110-starfive-visionfive-2-v1.3b.dtb/jh7110-starfive-visionfive-2-v1.2a.dtb)
+
+Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)
+
+.. code-block:: bash
+
+ sudo sgdisk --clear \
+ --set-alignment=2 \
+ --new=1:4096:8191 --change-name=1:spl --typecode=1:2E54B353-1271-4842-806F-E436D6AF6985\
+ --new=2:8192:16383 --change-name=2:uboot --typecode=2:BC13C2FF-59E6-4262-A352-B275FD6F7172 \
+ --new=3:16384:1654784 --change-name=3:system --typecode=3:EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 \
+ /dev/sdb
+
+Program the SD card
+
+.. code-block:: bash
+
+ sudo dd if=u-boot-spl.bin.normal.out of=/dev/sdb1
+ sudo dd if=u-boot.itb of=/dev/sdb2
+
+ sudo mount /dev/sdb3 /mnt/
+ sudo cp u-boot-spl.bin.normal.out /mnt/
+ sudo cp u-boot.itb /mnt/
+ sudo cp Image.gz /mnt/
+ sudo cp initramfs.cpio.gz /mnt/
+ sudo cp jh7110-starfive-visionfive-2-v1.3b.dtb /mnt/
+ sudo umount /mnt
+
+Booting
+~~~~~~~
+
+Change DIP switches MSEL[1:0] are set to 10, select the boot mode to SD.
+Once you plugin the sdcard and power up, you should see the U-Boot prompt.

+Booting from SPI
+----------------
+
+Use Building steps from "Booting from MMC using U-Boot SPL" section.
+
+Partition the SPI in Linux via mtdblock. (Require to boot the board in
+SD boot mode by enabling MTD block in Linux)
+
+Use prebuilt image from here [1], which support to partition the SPI flash.
+
+
+Program the SPI (Require to boot the board in SD boot mode)
+
+Execute below steps on U-Boot proper,
+
+.. code-block:: none
+
+ sf probe
+ fatload mmc 1:3 $kernel_addr_r u-boot.itb
+ sf update $kernel_addr_r 0x100000 $filesize
+
+ fatload mmc 1:3 $kernel_addr_r u-boot-spl.bin.normal.out
+ sf update $kernel_addr_r 0x0 $filesize
+
+
+Power off the board
+
+Change DIP switches MSEL[1:0] are set to 00, select the boot mode to flash
+
+Power up the board.
