> architectures that don't support NEON (they often lack them in Marvell and Allwinner).
I'm probably nitpicking here, but:
* All Allwinner SoCs have NEON[0]
* Most current ARMv7 processors have NEON. Of the current ARM cores, only Cortex-A5 and Cortex-A9 don't have mandatory NEON support (it's optional). Cortex-A5 is intended for embedded applications. Of the existing Cortex-A9 processors, AFAIK the only somewhat popular one without NEON support is NVIDIA Tegra 2, which is retired. Out of the third party cores, all Qualcomm and Apple ones have NEON support.
