Commit Message

Romain Naour Jan. 31, 2024, 5:38 p.m. UTC 
This patch adds a basic support for AM574x Industrial Development Kit
[1].

Use multi_v7_defconfig as kernel configuration file instead of
the deprecated omap2plus_defconfig [2].

The main differences between upstream kernels and the TI vendor tree
(5.10.x based) are:

  - pru based 100M ethernet ports will not work with upstream kernels
  since the prueth driver for AM57 is not upstream yet (as of 6.8-rc2)
  [3].

  - The ARM/DSP examples provided by TI [4] will not work either since
  they requires an experimental patch [5] adding "remote-processor
  messaging sockets".

  - There is no support for the POWERVR GPU SGX544 that requires
  additional userpace vendor (closed source) libraries.

It looks good to me and I've build tested it using docker-run.
