+
+TH1520 RISC-V SoC
+-----------------
+
+The TH1520 SoC consist of quad-core RISC-V Xuantie C910 (RV64GCV) processor,
+Xuantie C906 audio DSP, low power Xuantie E902 core, it also integrate
+Imagination GPU for graphics, and 4 TOPS NPU for AI acceleration.
+
+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:: none
+
+   export CROSS_COMPILE=<riscv64 toolchain prefix>
+
+The U-Boot is capable of running in M-Mode, so we can directly build it.
+
+.. code-block:: console
+
+	cd <U-Boot-dir>
+	make th1520_lpi4a_defconfig
+	make
+
+This will generate u-boot-dtb.bin
+
+Booting
+~~~~~~~
+
+Currently, we rely on vendor u-boot to initialize the clock, pinctrl subsystem,
+and chain load the mainline u-boot image either via tftp or emmc storage,
+then bootup from it.
