     I am using "u-boot version 2011-12" shared by Mr. Govind (ti) which 
was 1st updated by him.. I have also tried with the latest git: 
"u-boot-2012.07-rc1" but it is poping with "error : 
v7_dcache_inval_range - start address is not aligned". Do we have any 
solution for this. As i have also tried with Externally powered usb hub 
but it does not even initializes with it. Although i can see the device 
Name in u"usb tree".
         Any suggestion or solutions are always welcome.

Thanks & Regards
Atul Kumar
