The i.MX8M Mini is new SOC of the i.MX8M family. it is focused on delivering the latest and greatest video and audio experience combining state-of-the-art media-specific features with high-performance processing while optimized for lowest power consumption. The i.MX 8M Mini Media Applications Processor is 14nm FinFET product of the growing i.MX8M family targeting the consumer & industrial market. It is built in 14LPP to achieve both high performance and low power consumption and relies on a powerful fully coherent core complex based on a quad Cortex-A53 cluster with video and graphics accelerators this patch add the basic support for i.MX8MM.

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.

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.
|
|
Target_SoC should be "imx8mm" for i.MX8MM 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.
