From 83b3c2f4e06b5c666df523c9280d2cdf064e6d40 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 20 Jul 2009 16:37:30 -0400 Subject: avr32/microblaze/vax: punt local byteswap.h These arches are generic C implementations of the byteswap functions, so rather than keep a useless local copy, use the common C one.
