Unfortunately, it is a little different - it uses a DaVinci DM355 
processor, which is an ARM9 + custom DSP. The beagleboard uses an OMAP3x 
of course. Unfortunately, even I am confused on the TI naming scheme as 
to what is an OMAP versus what is a DaVinci.

I will probably do as you suggest - start with the beagleboard configs 
and also look at the leopardboard code in the ti u-boot repo. Hopefully 
that will give me enough data to get the basic barebox running.

The USB worries me, since I am just familiar enough with it to know how 
complex it can be. Time will tell.

Thank you for your input.
