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
