Rejected.

This is not a problem in U-Boot, but in your Linux driver.  The  rule
is  that  U-boot  will  initialize  ONLY  that hardware which it uses
itself, and it may even de-initialize the hardare after use. A  Linux
driver  must  not  make  any  assumptions about initialization of the
hardware done or not doen in the boot loader. It  is  resposnible  to
initialize the hardware to a usable state itself.

Please split the patch and resubmit only the last 2 items.

In general, please don't combine unrelated modifications in a  single
patch.

Thanks.

Best regards,

Wolfgang Denk
