+Rockchip SoCs
+=============
+
+Trusted Firmware-A supports a number of Rockchip ARM SoCs from both
+AARCH32 and AARCH64 fields.
+
+This includes right now:
+-  px30: Quad-Core Cortex-A53
+-  rk3288: Quad-Core Cortex-A17 (past A12)
+-  rk3328: Quad-Core Cortex-A53
+-  rk3368: Octa-Core Cortex-A53
+-  rk3399: Hexa-Core Cortex-A53/A72
+
+
+Boot Sequence
+-------------
+
+For AARCH32:
+    Bootrom --> BL1/BL2 --> BL32 --> BL33 --> Linux kernel
+
+For AARCH64:
+    Bootrom --> BL1/BL2 --> BL31 --> BL33 --> Linux kernel
+
+BL1/2 and BL33 can currently be supplied from either:
+-  Coreboot + Depthcharge
+-  U-Boot - either separately as TPL+SPL or only SPL
+
+
+How to build
+------------
+
+Rockchip SoCs expect TF-A's BL31 (AARCH64) or BL32 (AARCH32) to get
+integrated with other boot software like U-Boot or Coreboot, so only
+these images need to get build from the TF-A repository.
+
+For AARCH64 architectures the build command looks like
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl32
+
+while AARCH32 needs a slightly different command
+
+    make ARCH=aarch32 CROSS_COMPILE=arm-linux-gnueabihf- PLAT=rk3288 AARCH32_SP=sp_min bl32
+
+Both need replacing the PLAT argument with the platform from above you
+want to build for and the CROSS_COMPILE argument with you cross-
+compilation toolchain.
+
+
+How to deploy
+-------------
+
+Both upstream U-Boot and Coreboot projects contain instructions on where
+to put the built images during their respective build process.
+So after successfully building TF-A just follow their build instructions
+to continue.
