I never even heard of this chip. I think adding support for it should be ok, but we might remove it in the future should non trivial architecture changes become necessary and nobody cares for updating this.

We should somewhere have a board with this chip in the archive: http://www.phytec.de/de/produkte/module-im-ueberblick/phycore/produktdetails/p/phycore-at91m55800a.html Marko, are you working with a recent mainline kernel on this cpu? I'm wondering about the mmu-less state of the kernel.

I'm just starting work on that, so not quite sure how that's going to go. If you mean barebox then yes. I'm using fairly new code, I had to make some modifications to bypass dealing with cache and MMU as this chip does not have support for it. The changes were minor. I will go through my revisions and make sure it conforms to how everything else is done in this project and see about merging it in.
