+HiFive Unleashed
+================
+
+FU540-C000 RISC-V SoC
+---------------------
+The FU540-C000 is the world’s first 4+1 64-bit RISC-V SoC from SiFive.
+
+The HiFive Unleashed development platform is based on FU540-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 MMC using FSBL
+---------------------------
+
+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>
+
+3. make sifive_fu540_defconfig
+4. make
+
+Flashing
+~~~~~~~~
+
+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.bin in S-mode and provide M-mode runtime services.
+
+Currently, the u-boot.bin is used as a payload of the OpenSBI FW_PAYLOAD
+firmware. We need to compile OpenSBI with below command:
+
+.. code-block:: none
+
+	make PLATFORM=generic FW_PAYLOAD_PATH=<path to u-boot-dtb.bin>
+
+More detailed description of steps required to build FW_PAYLOAD firmware
+is beyond the scope of this document. Please refer OpenSBI documenation.
+(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
+
+Once the prior stage firmware/bootloader binary is generated, it should be
+copied to the first partition of the sdcard.
+
+.. code-block:: none
+
+    sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024
+
+Booting
+~~~~~~~
+
+Once you plugin the sdcard and power up, you should see the U-Boot prompt.

+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
+	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_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 \

+
+Booting

+
+Once you plugin the sdcard and power up, you should see the U-Boot prompt.

+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.
