By taking GENERIC_IOREMAP method, the generic ioremap_prot() and
iounmap() are visible and available to arch. Arch only needs to
provide implementation of arch_ioremap() or arch_iounmap() if there's
arch specific handling needed in its ioremap() or iounmap(). This
change will simplify implementation by removing duplicated codes with
generic ioremap() and iounmap(), and has the equivalent functioality
as before.
For SuperH, add hook arch_ioremap() and arch_iounmap for sh's special
operation when ioremap() and iounmap(), then ioremap_cache() is converted
to use ioremap_prot() from GENERIC_IOREMAP.
Meanwhile, add macro definitions for port|mm io functions since SuperH
has its own implementation in arch/sh/kernel/iomap.c and
arch/sh/include/asm/io_noioport.h. These will conflict with the port|mm io
function definitions in include/asm-generic/io.h to cause compiling
errors like below:
