From 23ff8633fd8ca75d2ffd4595b9c72bb1a5fdbd20 Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Tue, 12 Jan 2016 21:48:25 +0100 Subject: MIPS: sync I/O related header files with linux-4.4 Mainly sync asm/io.h to get a working ioremap() implementation as well as the full set of I/O accessors. Pull in additional header files to make this work. Furthermore port over the directory 'arch/mips/include/asm/mach-generic/' with contains default definitions for I/O and memory spaces and default implementations for mapping those spaces. All files in that directory can be overwritten by a SoC/machine.
