+Booting from MMC using U-Boot SPL +---------------------------------
+Building +--------
+Before building U-Boot SPL, OpenSBI must be built first. OpenSBI can be +cloned and built for FU540 as below:
+.. code-block:: console
git clone https://github.com/riscv/opensbi.gitcd opensbimake PLATFORM=generic FW_DYNAMIC=y+Copy OpenSBI FW_DYNAMIC image +(build/platform/sifive/fu540/firmware/fw_dynamic.bin) into U-Boot +root directory
The path for fw_dynamic.bin should be: build/platform/generic/firmware/fw_dynamic.bin
+.. code-block:: console
cp build/platform/sifive/fu540/firmware/fw_dynamic.bin <u-boot-dir>
Same as above.
+Now build the U-Boot SPL and U-Boot proper
+.. code-block:: console
cd <U-Boot-dir>make sifive_fu540_defconfigmake+This will generate spl/u-boot-spl.bin and FIT image (u-boot.itb)
+Flashing +--------
+ZSBL loads the U-Boot SPL (u-boot-spl.bin) from a partition with GUID type +5B193300-FC78-40CD-8002-E86C45580B47
+U-Boot SPL expects a U-Boot FIT image (u-boot.itb) from a partition with GUID +type 2E54B353-1271-4842-806F-E436D6AF6985
+FIT image (u-boot.itb) is a combination of fw_dynamic.bin, u-boot-nodtb.bin and +device tree blob (hifive-unleashed-a00.dtb)
+Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)
+.. code-block:: none
