- * ColdFire DMA Model:
- * ColdFire DMA supports two forms of DMA: Single and Dual address. Single
- * address mode emits a source address, and expects that the device will either
- * pick up the data (DMA READ) or source data (DMA WRITE). This implies that
- * the device will place data on the correct byte(s) of the data bus, as the
- * memory transactions are always 32 bits. This implies that only 32 bit
- * devices will find single mode transfers useful. Dual address DMA mode
- * performs two cycles: source read and destination write. ColdFire will
- * align the data so that the device will always get the correct bytes, thus
- * is useful for 8 and 16 bit devices. This is the mode that is supported
- * below.
- *
- * AUG/22/2000 : added support for 32-bit Dual-Address-Mode (K) 2000
- * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
- *
- * AUG/25/2000 : added support for 8, 16 and 32-bit Single-Address-Mode (K)2000
- * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
- *
- * APR/18/2002 : added proper support for MCF5272 DMA controller.

- * destination the set_dma_device_addr value. Otherwise the source will be set to the
- * set_dma_device_addr value and the destination will get the set_dma_addr value.

- * The other is to use the provided set_dma_src_addr and set_dma_dest_addr functions
