I think It should not be vfpv3-d16 with neon, but vfpv3-d32 with neon. That is, I think there's an error on AM437x Technical Reference Manual.
According to AM437x Technical Reference Manual, AM437x impletents NEON Processing Engine (NPE) and VFPv3-D16 simutanously,
which is not allowed according to Cotex-A9 Technical Reference Manual.
So, am I right? THX all
