Openwrt has whole implementation but I have no idea why it's not
in the official kernel.

Actually the same applies to ath9k because ATHEROS_AR71XX definition
needed for AHB is not specified in latest kernel.

I will make it exclusive and post in the the series if there are
no more comments.

Support for Atheros AR71xx chips has been submitted for review a couple of
days ago: http://www.linux-mips.org/archives/linux-mips/2010-11/msg00085.html

the Kconfig symbol name should be changed accordingly when the patches are
accepted.
