So, the problems are in openwrt platform patches that should be rewriten:
1. Changes needed to avoid using code like "mem=res->start" without ioremap.
2. Changes needed to avoid using NULL in first argument of
dma_alloc_coherent and others.

Without these changes ahb patch won't get into the kernel and we'll be
lack of wisoc devices support?
Is there any chance for the patch to get into the kernel and what
should be done for it?

(PS: Sorry for my english.)
