From 7525a9901b5ee3c84933ad069e41506c37404ddc Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Wed, 8 Jul 2015 23:10:06 -0400 Subject: [PATCH] m32r: Add ioreadXX/iowriteXX big-endian mmio accessors commit c627f2ceb692 ("serial: 8250: Add support for big-endian MMIO accesses") added support for 32-bit big-endian mmio to the 8250 driver. Support for ioreadXXbe/iowriteXXbe io accessors was missing from m32r arch, which caused build errors. Add trivial macro mmio accessors.
