[meta-freescale] i.MX6Q vs i.MX6UL tuning

I'm working with machines that have i.MX6Q/DL and i.MX6UL and noticed
that they have quite different tuning.

   TUNE_FEATURES     = "arm armv7a vfp thumb neon callconvention-hard cortexa9"
   TARGET_FPU        = "hard"

   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?
