I've been doing some Linux work with the 83xx DMA controller. The only real differences between the 83xx/85xx controller are the register endianness and snoop bits. The 83xx controller's registers are all little-endian, while the 85xx is all big-endian.
83xx DMA = Elo DMA controller 85xx/86xx DMA = Elo Plus DMA controller
The Elo Plus supports list descriptors in addition to link descriptors. The Elo only supports link descriptors.
