From 3f84dfc1cde5594500e2cee4b1db17c2fc1c2ab2 Mon Sep 17 00:00:00 2001 From: Adrian Chadd Date: Thu, 4 Feb 2016 22:39:27 +0000 Subject: [PATCH] Provide a workaround for setting the correct endianness when doing CFI on a mips big-endian board. This is (hopefully! ish!) a temporary change until a slightly better way can be found to express this without a config option.
