* NOTES about DMA transfers:
*
* controller 1: channels 0-3, byte operations, ports 00-1F
* controller 2: channels 4-7, word operations, ports C0-DF
*
* - ALL registers are 8 bits only, regardless of transfer size
* - channel 4 is not used - cascades 1 into 2.
* - channels 0-3 are byte - addresses/counts are for physical bytes
* - channels 5-7 are word - addresses/counts are for physical words
* - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
* - transfer count loaded to registers is 1 less than actual count
* - controller 2 offsets are all even (2x offsets for controller 1)
* - page registers for 5-7 don't use data bit 0, represent 128K pages
* - page registers for 0-3 use bit 0, represent 64K pages
*
* DMA transfers are limited to the lower 16MB of _physical_ memory.
* Note that addresses loaded into registers must be _physical_ addresses,
* not logical addresses (which may differ if paging is active).
*
* Address mapping for channels 0-3:
*
* A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
* | ... | | ... | | ... |
* | ... | | ... | | ... |
* | ... | | ... | | ... |
* P7 ... P0 A7 ... A0 A7 ... A0
* | Page | Addr MSB | Addr LSB | (DMA registers)
*
* Address mapping for channels 5-7:
*
* A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
* | ... | \ \ ... \ \ \ ... \ \
* | ... | \ \ ... \ \ \ ... \ (not used)
* | ... | \ \ ... \ \ \ ... \
* P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
* | Page | Addr MSB | Addr LSB | (DMA registers)
*
* Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
* and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
* the hardware level, so odd-byte transfers aren't possible).
*
* Transfer count (_not # bytes_) is limited to 64K, represented as actual
* count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
* and up to 128K bytes may be transferred on channels 5-7 in one operation.
