I have a board the use uart4 as a console. I'm working to have it as an option in omap3 code.

Are you going to post the board?

The product name is Morrison and I'm working on it. We are on pcb design and I'm working on the first sample trying to fix some problems. It is based on DM47xx cpu and I don't know if I will post the patches soon on it. This patch doesn't introduce any regression right now

This is an idea of what can be the uart clock enable for uart4.
