Thanks, I globally like this and find this much better than the
microblaze specific handling we had before. However, could you migrate
this nice cover letter description into the appropriate commit logs?
Your commit logs are really short and do not describe what the commit
is doing, but the commit logs is what is staying in the project
history, so this is where all the attention should be put, rather than
to the cover letter.

I'll reply to the individual patches for details.

Thanks!
