Current state of AM33xx patches

[Paul Walmsley]

Good news; am able to get it booting with the images you sent and by 
following the U-boot commands line by line from your earlier post. If I 
use the uEnv.txt to set the optargs and uenvcmd to the same values, it 
hangs as before.  So looks like I need to do a little further debugging 
there to see why that's not working.

Thanks for your help.
