Can you expand the description a bit more so it makes sense as a changelog
text for the merge commit? It's fairly rare these days that we add support for a
MMU-less platform, so it would be good if the introductory text answers
questions like:

- what is this platform used for, and what is the purpose of running Linux on it
  in place of the usual RTOS variants?

- are you doing this just for fun, or are there any commercial use cases?

- what are the minimum and maximum memory configurations this has
  been tested with?

- what user space are you testing with: any particular distro that supports
  this platform, and do you run elf-fdpic or flat binaries.

- are you planning to also support the newer i.MXRT11xx or
  Cortex-R based designs like the S32S?
