I'm working with machines that have i.MX6Q/DL and i.MX6UL and noticed
that they have quite different tuning.
i.MX6Q:
TUNE_FEATURES = "arm armv7a vfp thumb neon callconvention-hard cortexa9"
TARGET_FPU = "hard"
i.MX6UL:
TUNE_FEATURES = "arm armv7ve vfp thumb neon cortexa7"
TARGET_FPU = "softfp"
I've not adjusted any GCC tuning for these targets. Just wondering
why the i.MX6Q is hardfp and the i.MX6UL is soft? Anyone know why
this choice was made?
