freebsd/sys/dev/ata/ata-chipset.c
Søren Schmidt 566cf07a7c Second round of updates to the ATA driver. 
Clean up the DMA interface too much unneeded stuff crept in with
the busdma code back when.

Modify the ATA_IN* / ATA_OUT* macros so that resource and offset
are gotten from a table. That allows for new chipsets that doesn't
nessesarily have things ordered the good old way. This also removes
the need for the wierd PC98 resource functions.

Tested on: i386, PC98, Alpha, Sparc64
