Although we would need to do something about the sa1100-specific
physical addresses and register access for bankwidth (this could
probably go into the info passed from board files, there's a width field
of the flash_info struct), and perhaps the pxa2xx cache invalidate code,
but: yes, we're pretty close to a generic mapping driver for arches that
declare a include/asm/mach/flash.h compatible with ARM's. And there's
probably a need for an alternative to the current definition of struct
device's platform_data for these sorts of things, since many uses of
platform_data really hold info represented in generic data structures,
without a need for platform-specific definition or interpretation, so it
could be on all platforms. I might try to run that by folks sometime soon.
