14 * The ISD200 ASIC does not natively support ATA devices. The chip
15 * does implement an interface, the ATA Command Block (ATACB) which provides
16 * a means of passing ATA commands and ATA register accesses to a device.
20 * 2002-10-19: Removed the specialized transfer routines.
22 * 2001-02-24: Removed lots of duplicate code and simplified the structure.
24 * 2002-01-16: Fixed endianness bug so it works on the ppc arch.
26 * 2002-01-17: All bitfields removed.
