+Banana Pi F3
+============
+
+About This
+----------
+Banana Pi F3 board is a industrial grade RISC-V development board, it
+design with SpacemiT K1 8 core RISC-V chip, CPU integrates 2.0 TOPs AI
+computing power. 4G DDR and 16G eMMC onboard.2x GbE Ethernet prot, 4x USB
+3.0 and PCIe for M.2 interface, support HDMI and Dual MIPI-CSI Camera.
+
+Building
+~~~~~~~~
+1. Add the RISC-V toolchain to your PATH.
+2. Setup ARCH & cross compilation environment variable:
+
+.. code-block:: console
+
+   export CROSS_COMPILE=<riscv64 toolchain prefix>
+
+3. Before building U-Boot, OpenSBI should be built first. OpenSBI can be
+built for SpacemiT K1 SoC as below:
+
+.. code-block:: console
+
+   git clone https://github.com/cyyself/opensbi -b k1-opensbi
+   cd opensbi
+   make PLATFORM=generic
+
+4. Then build U-Boot as following:
+
+.. code-block:: console
+
+   cd <U-Boot-dir>
+   make bananapi_f3_defconfig
+   make OPENSBI=<OpenSBI-dir>/build/platform/generic/firmware/fw_dynamic.bin
+
+This will generate u-boot.itb
+
+Booting
+~~~~~~~
+Currently, we use a modified vendor's U-Boot SPL to load a FIT image that
+includes OpenSBI and U-Boot. Fully describing how to boot into U-Boot is a
+challenging task. And the booting method will be added after the SPL
+support is available.
