20 * NOTES about DMA transfers:
21 *
22 * controller 1: channels 0-3, byte operations, ports 00-1F
23 * controller 2: channels 4-7, word operations, ports C0-DF
24 *
25 * - ALL registers are 8 bits only, regardless of transfer size
26 * - channel 4 is not used - cascades 1 into 2.
27 * - channels 0-3 are byte - addresses/counts are for physical bytes
28 * - channels 5-7 are word - addresses/counts are for physical words
29 * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
30 * - transfer count loaded to registers is 1 less than actual count
31 * - controller 2 offsets are all even (2x offsets for controller 1)
32 * - page registers for 5-7 don't use data bit 0, represent 128K pages
33 * - page registers for 0-3 use bit 0, represent 64K pages
34 *
35 * DMA transfers are limited to the lower 16MB of _physical_ memory.
36 * Note that addresses loaded into registers must be _physical_ addresses,
37 * not logical addresses (which may differ if paging is active).
38 *
39 * Address mapping for channels 0-3:
40 *
41 * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
42 * | ... | | ... | | ... |
43 * | ... | | ... | | ... |
44 * | ... | | ... | | ... |
45 * P7 ... P0 A7 ... A0 A7 ... A0
46 * | Page | Addr MSB | Addr LSB | (DMA registers)
47 *
48 * Address mapping for channels 5-7:
49 *
50 * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
51 * | ... | \ \ ... \ \ \ ... \ \
52 * | ... | \ \ ... \ \ \ ... \ (not used)
53 * | ... | \ \ ... \ \ \ ... \
54 * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
55 * | Page | Addr MSB | Addr LSB | (DMA registers)
56 *
57 * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
58 * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
59 * the hardware level, so odd-byte transfers aren't possible).
60 *
61 * Transfer count (_not # bytes_) is limited to 64K, represented as actual
62 * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
63 * and up to 128K bytes may be transferred on channels 5-7 in one operation.
64 *
