+Description
+===========
+
+The i.MX 8M family of applications processors based on Arm Corte-A53 and Cortex-M4
+cores provide high-performance computing, power efficiency, enhanced system
+reliability and embedded security needed to drive the growth of fast-growing
+edge node computing, streaming multimedia, and machine learning applications.
+
+Boot Sequence
+=============
+
+Bootrom --> SPL --> BL31 --> BL33(u-boot) --> Linux kernel
+
+How to build
+============
+
+Build Procedure
+---------------
+
+-  Prepare AARCH64 toolchain.
+
+-  Build spl and u-boot firstly, and get binary images: u-boot-spl.bin,
+   u-boot-nodtb.bin and dtb for the target board.
+
+-  Build TF-A
+
+   Build bl31:
+
+   .. code:: shell
+
+       CROSS_COMPILE=aarch64-linux-gnu- make PLAT=<Target_SoC> bl31
+
+   Target_SoC should be "imx8mq" for i.MX8MQ SoC.
+
+Deploy TF-A Images
+-----------------
+
+TF-A binary(bl31.bin), u-boot-spl.bin u-boot-nodtb.bin and dtb are combined
+together to generate a binary file called flash.bin, the imx-mkimage tool is
+used to generate flash.bin, and flash.bin needs to be flashed into SD card
+with certain offset for BOOT ROM. the u-boot and imx-mkimage will be upstreamed
+soon, this doc will be updated once they are ready, and the link will be posted.
