6 * ColdFire DMA Model:
7 * ColdFire DMA supports two forms of DMA: Single and Dual address. Single
8 * address mode emits a source address, and expects that the device will either
9 * pick up the data (DMA READ) or source data (DMA WRITE). This implies that
10 * the device will place data on the correct byte(s) of the data bus, as the
11 * memory transactions are always 32 bits. This implies that only 32 bit
12 * devices will find single mode transfers useful. Dual address DMA mode
13 * performs two cycles: source read and destination write. ColdFire will
14 * align the data so that the device will always get the correct bytes, thus
15 * is useful for 8 and 16 bit devices. This is the mode that is supported
16 * below.
17 *
18 * AUG/22/2000 : added support for 32-bit Dual-Address-Mode (K) 2000
19 * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
20 *
21 * AUG/25/2000 : addad support for 8, 16 and 32-bit Single-Address-Mode (K)2000
22 * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
23 *

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

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

9 * ColdFire DMA Model:
10 * ColdFire DMA supports two forms of DMA: Single and Dual address. Single
11 * address mode emits a source address, and expects that the device will either
12 * pick up the data (DMA READ) or source data (DMA WRITE). This implies that
13 * the device will place data on the correct byte(s) of the data bus, as the
14 * memory transactions are always 32 bits. This implies that only 32 bit
15 * devices will find single mode transfers useful. Dual address DMA mode
16 * performs two cycles: source read and destination write. ColdFire will
17 * align the data so that the device will always get the correct bytes, thus
18 * is useful for 8 and 16 bit devices. This is the mode that is supported
19 * below.
20 *
21 * AUG/22/2000 : added support for 32-bit Dual-Address-Mode (K) 2000
22 * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
23 *
24 * AUG/25/2000 : addad support for 8, 16 and 32-bit Single-Address-Mode (K)2000

22 * The 5272 ColdFire interrupt controller is nothing like any other
23 * ColdFire interrupt controller - it truly is completely different.
24 * Given its age it is unlikely to be used on any other ColdFire CPU.

28 * The masking and priproty setting of interrupts on the 5272 is done
29 * via a set of 4 "Interrupt Controller Registers" (ICR). There is a
30 * loose mapping of vector number to register and internal bits, but
31 * a table is the easiest and quickest way to map them.
