BTW, the Acqua is a SAMA5D3[1] (SAMA5D31 or SAMA5D36, depending on the version), not a SAMA5D2. The datasheet[2] of the SAMA5D3 states: The Floating-Point Unit (FPU) supports the ARMv7 VFPv4-D16 architecture without Advanced SIMD extensions (NEON). So I guess the patch is not relevant to this board.
