The APB DMA is more of a generic DMA and so for memcpy it would seem to be a good choice and it is available on all Tegras not just Tegra210. Furthermore, from a power standpoint the ADMA is in the audio power domain and so using it for memcpy would mean the audio power domain is turned on. It may not be a big deal for some, but given the APB is in the CORE domain (always on when not in low-power) it seems like a better choice for power as well.
