+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.git
+ cd opensbi
+ make PLATFORM=generic FW_DYNAMIC=y
+
+Copy OpenSBI FW_DYNAMIC image
+(build/platform/sifive/fu540/firmware/fw_dynamic.bin) into U-Boot
+root directory
+
+.. code-block:: console
+
+ cp build/platform/sifive/fu540/firmware/fw_dynamic.bin <u-boot-dir>
+
+Now build the U-Boot SPL and U-Boot proper
+
+.. code-block:: console
+
+ cd <U-Boot-dir>
+ make sifive_fu540_defconfig
+ make
+
+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
+
+ # sudo sgdisk --clear \
+ > --set-alignment=2 \
+ > --new=1:34:2081 --change-name=1:loader1 --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \
+ > --new=2:2082:10273 --change-name=2:loader2 --typecode=2:2E54B353-1271-4842-806F-E436D6AF6985 \
+ > --new=3:10274: --change-name=3:rootfs --typecode=3:0FC63DAF-8483-4772-8E79-3D69D8477DE4 \
+ > /dev/sda
+
+Program the SD card
+
+.. code-block:: none
+
+ sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=34
+ sudo dd if=u-boot.itb of=/dev/sda seek=2082
+
+Booting
+-------
+Once you plugin the sdcard and power up, you should see the U-Boot prompt.
