+Milk-V Duo
+==========
+
+CV1800B RISC-V SoC
+------------------
+The CV1800B is a high-performance, low-power 1+1 64-bit RISC-V SoC from Sophgo.
+
+Mainline support
+----------------
+The support for following drivers are already enabled:
+1. ns16550 UART Driver.
+
+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>
+ cd <U-Boot-dir>
+ make milkv_duo_defconfig
+ make
+
+This will generate u-boot-dtb.bin
+
+Booting
+~~~~~~~
+Currently, we rely on vendor FSBL(First Stage Boot Loader) to initialize the
+clock and load the u-boot image, then bootup from it.
+
+Sample boot log from Milk-V Duo board
