jdolecek | fix off-by-one in the mapping of the ISA DMA page registers, they actually
start at 0x81; the code used bus_space_map() starting from 0x80 but
used +1 offset for actual I/O, now it maps starting 0x81 and does I/O
without offset
the reads and writes work exactly the same as before, but this frees
0x80 for being mapped independantly
patch provided in PR kern/52468 by Jonathan Chapman; checked against the spec
and also FreeBSD sys/x86/isa/isa_dma.c

thorpej | branches: 1.7.126; 1.7.128; 1.7.130;
Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns
the maximum transfer size for the specified DMA channel. Make all clients
of ISA DMA use this call to determine their maximum transfer size.

add definitions for the mask registers. fix I/O size definitions.

note that most of dev/ic's contents have changed names

mycroft | Separate DMA functions.
|
| 1.4.12.1 |

thorpej | Mostly-rewrite, converting the ISA DMA controller driver to be a user
of the bus dma API. A new isa_dma*() function call interface is exported
to drivers that need to use this controller.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
