From a8433137ea9143bb3a2bc18a3407b5a130fdb868 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Fri, 17 Feb 2006 01:36:24 +0900 Subject: [MIPS] Make I/O helpers more customizable 1. Move ioswab*() and __mem_ioswab*() to mangle-port.h. This gets rid of CONFIG_SGI_IP22 from include/asm-mips/io.h. 2. Pass a virtual address to *ioswab*(). Then we can provide mach-specific *ioswab*() and can do every evil thing based on its argument. It could be useful on machines which have regions with different endian conversion scheme. 3. Call __swizzle_addr*() _after_ adding mips_io_port_base. This unifies the meaning of the argument of __swizzle_addr*() (always virtual address). Then mach-specific __swizzle_addr*() can do every evil thing based on the argument.
