As pointed by SAMA5D2 Datasheet[1]: ``` The Cortex-A5 NEON Media Processing Engine (MPE) extends the Cortex-A5 functionality to provide support for the ARM v7 Advanced SIMD v2 and Vector Floating-Point v4 (VFPv4) instruction sets. ``` So let's enable VFPV4/NEON FPU strategy instead of the default VFPV4-D16.
