From 6752d4cb08b734235bd7978424087514623696b0 Mon Sep 17 00:00:00 2001 From: Luka Perkov Date: Thu, 27 Feb 2014 22:41:39 +0000 Subject: imx6: enable FPU for hard float The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration. As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu to the feature list. This will default the IMX6 target to use -mfloat-abi=hard which will the be most efficient use of floating point. When switching to hard float, we also need to enable VFP support in the kernel.
