I am fixing an addition that I created.

I am testing using an appended device-tree. This has been the most
reliable method for the OMAP34XX boards that I have. If you have an
example config, with working command line MTDPARTS, for beagleboard(Rev.
C4), Overo TOBI, or similiar OMAP34XX, I will gladly use it. Also note
that other OMAP34XX boards currently provide a default partition
layout. Is that bad practice for all of those as well? I am open to
exploring the method that actually works.
