[RFC][PATCH 09/10] bcm47xx: add support for bcma bus

["Rafał Miłecki" <zajec5@gmail.com>]

2011/6/6 Hauke Mehrtens <hauke@hauke-m.de>:
> This patch add support for the bcma bus. Broadcom uses only Mips 74K
> CPUs on the new SoC and on the old ons using ssb bus there are no Mips
> 74K CPUs.

I'm not involved in development for embedded devices but I believe
that space is quite important for them.

You force compiling both: ssb and bcma for every device using bcm47xx.
I think ppl may want to compile only one bus driver.
