X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f7f117b88df3728c116902c29b04b59b38600633;p=openwrt%2Fstaging%2Flinusw.git

imx6: optimize for NEON FPU hardware

The IMX6 SoC uses an ARM Cortext-A9 which has both NEON and VFPv3 hardware
blocks.  This will tune gcc to use neon instead of vfpv3 which will outperform
VFPv3.
