From 2da81fa80c4cd965f05ad237d81d9764322fde20 Mon Sep 17 00:00:00 2001 From: Paul Sokolovsky Date: Fri, 11 Apr 2014 03:44:00 +0300 Subject: [PATCH] mpconfig.h: Add basic support for target endianness configuration. A specific target can define either MP_ENDIANNESS_LITTLE or MP_ENDIANNESS_BIG to 1. Default is MP_ENDIANNESS_LITTLE.
