From ed7c73fbefe240a6e3bcee4ebcbbe333f718b762 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 7 Jun 2014 17:36:02 +0000 Subject: brcm47xx: activate some compiler optimizations for 74K CPUs With this patch the mips74k subtarget will be compiled with optimized compiler options to generated smaller and faster code. This currently breaks broadcom-wl, because the binary blob is only compiled with mipsr1 support.
