2008-03-30fix the broken annotations in fsldmaAl Viro
a) every bitwise declaration will give a unique type; use typedefs. b) no need to bother with the stuff pointed to by iomem pointers, unless it's accessed directly. noderef will force us to use helpers anyway.

2008-03-18fsldma: Fix the DMA halt when using DMA_INTERRUPT async_tx transfer.Zhang Wei
The DMA_INTERRUPT async_tx is a NULL transfer, thus the BCR(count register) is 0. When the transfer started with a byte count of zero, the DMA controller will triger a PE(programming error) event and halt, not a normal interrupt. I add special codes for PE event and DMA_INTERRUPT async_tx testing.

2008-03-04dmaengine: add driver for Freescale MPC85xx DMA controllerZhang Wei
The driver implements DMA engine API for Freescale MPC85xx DMA controller, which could be used by devices in the silicon. The driver supports the Basic mode of Freescale MPC85xx DMA controller. The MPC85xx processors supported include MPC8540/60, MPC8555, MPC8548, MPC8641 and so on. The MPC83xx(MPC8349, MPC8360) are also supported.
