The blackfin architecture is getting removed, and this is the last remaining architecture specific setting, so the various hacks can be removed now.
From all I can tell, there are no remaining in-tree users of the driver, but it could be used by out-of-tree platform ports. I've marked the driver as 'depends on COMPILE_TEST', short of removing it outright.
It was originally written for some ARM PXA machines using the same chip, but that platform never really worked and the code has been removed a long time ago.
