Hi Artur!
Thanks a lot for your patches!

Wow, that sounds great! I will be happy to review your patches.

Yes, there is still a lot of modernization work to be done for SuperH!
Device tree has actually been worked on in the past and there is a patch set by Yoshinori Sato to add support for device tree that got never merged, see [1].
Geert and I are planning to have another look at these patches and see whether we can get them into a shape where they can be merged. Maybe you can help us with that effort.
I might not have the time for your patches today, but certainly next week starting Monday. Very much looking forward to reviewing and merging them into my SuperH tree [2].
Adrian
