From 04efda7afca03692dd7335d1205211c302d502a4 Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Mon, 28 Mar 2011 18:33:56 +0200 Subject: MIPS: Optimize the setup of CPU optimization flags The current MIPS CPU config.mk code always expects a MIPS 4kc core. This is not appropiate for other CPUs and SoCs. Replace the current MIPSFLAGS code by cc-option macro and use -march=mips32r2 as default optimization level for all MIPS32 CPUs. Note: Since commit f62fb99941c625605aa16a0097b396a5c16d2c88 all toolchains with binutils prior to v2.16 are not working anymore. As agreed with Shinya Kuribayashi the support for those toolchains will be dropped officially with this patch.
