+Subject: [PATCH] mips: Remove default endiannes
+
+Currently, trying to build ci20_mmc fails on little-endian
+toolchains. The problem seems to be that some targets don't
+have CONFIG_SYS_LITTLE_ENDIAN properly set, and therefore
+the default -EB switch is selected.
+
+Let's get rid of the default switch entirely, and fix this problem.
+While this may be a hack, it is a quick solution until
+U-Boot gets CI20 proper support.
