Umm, if the BSCR is really so unique to each board, how come this
driver is frobbing a specific bit?  How does the ucc_geth driver know
about the layout of a given board's BCSR?

Also, this patch means that the kernel won't build (assuming you have
the ucc_geth driver in your config) until we get to patch 9/15, where
get_bcsr gets defined.

Lastly, shouldn't this patch be going through Jeff Garzik?
