[meta-freescale] What's the different between gpu-viv-bin-mx6q-hfp and gpu-viv-bin-mx6q-sfp

[kongling]

Hi, everyone

   There are "hfp" and "sfp" libs in gpu-viv-bin-mx6q-3.10.17-1.0.0.
   Could anyone tell me what's the different between hfp andg sfp?
   For board mcimx6q-sdb,which libs should I use?

   I build "core-image-weston" with yocto imx-3.10.31-1.1.0_beta.It was hf by default.
   Could anyone tell me how to build the sf version?

BR,

kongling
