-Subject: [PATCH] memcpy: don't use optimized for VFP/NEON versions
-
-Tests with the tinymembench tool on a Colibri T30 show the performance
-of the standard arm based memcpy to be around 2 times faster than
-__memcpy_neon or __memcpy_vfp.
-
-Tests on Apalis iMX6 confirm this, although running only around 1.3 times faster.
