[PATCH] ide: Stop mapping ROMs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Various old IDE drivers go mapping ROM devices for no apparent reason and
without using the ROM mapping API we now have. They don't actually use
the ROM they map and the new libata drivers are happy without it being
mapped so rather than port them lets just junk it for the next -rc1.
