4 | * |
5 | * Current development and maintenance: |
6 | * (C) 2001-2002 Björn Stenberg (bjorn@haxx.se) |
7 | * |
8 | * Developed with the assistance of: |
9 | * (C) 2002 Alan Stern <stern@rowland.org> |
10 | * |
11 | * Initial work: |
12 | * (C) 2000 In-System Design, Inc. (support@in-system.com) |
13 | * |
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. |
17 | * |
18 | * History: |
19 | * |
20 | * 2002-10-19: Removed the specialized transfer routines. |
21 | * (Alan Stern <stern@rowland.harvard.edu>) |
22 | * 2001-02-24: Removed lots of duplicate code and simplified the structure. |
23 | * (bjorn@haxx.se) |
24 | * 2002-01-16: Fixed endianness bug so it works on the ppc arch. |
25 | * (Luc Saillard <luc@saillard.org>) |
26 | * 2002-01-17: All bitfields removed. |
