> +Running U-Boot SPL
> +------------------
> +The U-Boot SPL will boot in M mode and load the FIT image which include
> +OpenSBI and U-Boot proper images. After loading progress, it will jump
> +to OpenSBI first and then U-Boot proper which will run in S mode.
> +
> +
> +How to build U-Boot SPL
> +-----------------------
> +Before building U-Boot SPL, OpenSBI must be build first. OpenSBI can be
> +cloned and build for FU540 as below:
> +
Please add
.. code-block:: console
> +git clone https://github.com/riscv/opensbi.git
> +cd opensbi
> +make PLATFORM=sifive/fu540
> +
> +Copy OpenSBI FW_DYNAMIC image
> +(build/platform/sifive/fu540/firmware/fw_dynamic.bin)
> +into U-Boot root directory
> +
> +
> +How to build U-Boot SPL booting from MMC
> +----------------------------------------
> +With sifive_fu540_spl_defconfig:
> +
> +1. Add the RISC-V toolchain to your PATH.
> +2. Setup ARCH & cross compilation enviornment variable:
> +
> +.. code-block:: none
> +
> + export ARCH=riscv
> + export CROSS_COMPILE=<riscv64 toolchain prefix>
> +
> +3. make sifive_fu540_spl_defconfig
> +4. make
> +
> +
> +Flashing
> +--------
> +
> +The current U-Boot port is supported in S-mode only.
> +
> +A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
> +boot the u-boot.bin in S-mode and provide M-mode runtime services.
> +
> +First partition of the sdcard should contain "u-boot.itb" and Partition
> +type should be of "8300 Linux filesystem".
> +
> +.. code-block:: none
> +
> + sudo dd if=spl/u-boot-spl.bin of=/dev/disk2s4 bs=1024
> + sudo dd if=u-boot.itb of=/dev/disk2s1 bs=1024
> +
> +Booting
> +-------
> +Once you plugin the sdcard and power up, you should see the U-Boot prompt.
