Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
