From 92a8ed4c7643809123ef0a65424569eaacc5c6b0 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Tue, 29 Dec 2015 14:54:19 -0800 Subject: [PATCH] m32r: add io*_rep helpers m32r allmodconfig was failing with the error: error: implicit declaration of function 'read' On checking io.h it turned out that 'read' is not defined but 'readb' is defined and 'ioread8' will then obviously mean 'readb'. At the same time some of the helper functions ioreadN_rep() and iowriteN_rep() were missing which also led to the build failure.
