* An ATA driver for the legacy ATA ports.
*
* Data Sources:
* Opti 82C465/82C611 support: Data sheets at opti-inc.com
* HT6560 series:
* Promise 20230/20620:
* http://www.ryston.cz/petr/vlb/pdc20230b.html
* http://www.ryston.cz/petr/vlb/pdc20230c.html

*
* Unsupported but docs exist:
* Appian/Adaptec AIC25VL01/Cirrus Logic PD7220
*
* This driver handles legacy (that is "ISA/VLB side") IDE ports found
* on PC class systems. There are three hybrid devices that are exceptions
* The Cyrix 5510/5520 where a pre SFF ATA device is on the bridge and
* the MPIIX where the tuning is PCI side but the IDE is "ISA side".
*
* Specific support is included for the ht6560a/ht6560b/opti82c611a/
* opti82c465mv/promise 20230c/20630/winbond83759A
*
* Use the autospeed and pio_mask options with:
* Appian ADI/2 aka CLPD7220 or AIC25VL01.
* Use the jumpers, autospeed and set pio_mask to the mode on the jumpers with
* Goldstar GM82C711, PIC-1288A-125, UMC 82C871F, Winbond W83759,
* Winbond W83759A, Promise PDC20230-B
*
* For now use autospeed and pio_mask as above with the W83759A. This may
* change.
