+HiFive Unmatched
+================
+
+FU740-C000 RISC-V SoC
+---------------------
+The FU740-C000 is a 4+1 64-bit RISC-V core SoC from SiFive.
+
+The HiFive Unmatched development platform is based on FU740-C000 and capable
+of running Linux.
+
+Mainline support
+----------------
+The support for following drivers are already enabled:
+
+1. SiFive UART Driver.
+2. SiFive PRCI Driver for clock.
+3. Cadence MACB ethernet driver for networking support.
+4. SiFive SPI Driver.
+5. MMC SPI Driver for MMC/SD support.
+
+Booting from uSD using U-Boot SPL
+---------------------------------
+
+Building
+--------
+
+Before building U-Boot SPL, OpenSBI must be built first. OpenSBI can be
+cloned and built for FU740 as below:
+
+.. code-block:: console
+
+	git clone https://github.com/riscv/opensbi.git
+	cd opensbi
+	make PLATFORM=generic
+	export OPENSBI=<path to opensbi/build/platform/generic/firmware/fw_dynamic.bin>
+
+Now build the U-Boot SPL and U-Boot proper
+
+.. code-block:: console
+
+	cd <U-Boot-dir>
+	make sifive_unmatched_defconfig
+	make
+
+This will generate spl/u-boot-spl.bin and 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 u-boot.itb from a partition with GUID
+type 2E54B353-1271-4842-806F-E436D6AF6985
+
+u-boot.itb is a combination of fw_dynamic.bin, u-boot-nodtb.bin and
+device tree blob (hifive-unmatched-a00.dtb)
+
+Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)
+
+.. code-block:: none
+
+	# sudo sgdisk -g --clear -a 1 \
+	> --new=1:34:2081         --change-name=1:spl --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \
+	> --new=2:2082:10273      --change-name=2:uboot  --typecode=2:2E54B353-1271-4842-806F-E436D6AF6985 \
+	> --new=3:16384:282623    --change-name=3:boot --typecode=3:0x0700 \
+	> --new=4:286720:13918207 --change-name=4:root --typecode=4:0x8300 \
+	> /dev/sdb
+
+Copy linux Image.gz and hifive-unmatched-a00.dtb to boot partition
+
+.. code-block:: none
+
+	sudo mkfs.vfat /dev/sdb3
+	sudo mkfs.ext4 /dev/sdb4
+
+	sudo mount /dev/sdb3 /media/sdb3
+	sudo cp Image.gz hifive-unmatched-a00.dtb /media/sdb3/
+
+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.
+
+
+Loading the kernel and dtb
+
+.. code-block:: none
+
+	fatload mmc 0:3 ${kernel_addr_r} Image.gz
+	fatload mmc 0:3 ${fdt_addr_r} hifive-unmatched-a00.dtb
+	booti ${kernel_addr_r} - ${fdt_addr_r}
