I just though of allowing the reset to take longer as I have no idea how 
long it could take, let alone other versions of OMAP.

Good point. On ARM ndelay(1) seems to be equal to udelay(1) at the moment.

I actually just removed the ndelay(1) and again, "delay" won't get past 
1 if I print it after the loop.

It'd be nice to know how it works on other OMAP versions before making 
such changes. :-)
