From 5831fdb099ddeec9849658cd534fdcbb03aa6ff9 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Sun, 20 Oct 2019 22:43:15 +0800 Subject: MIPS: Loongson2ef: clean up loongson64 related code Remove unrelevent macros, defines and codes from loongson2ef mach. Also rename some defines to match new naming.
