- * olympic.c (c) 1999 Peter De Schrijver All Rights Reserved
- * 1999/2000 Mike Phillips (mikep@linuxtr.net)
- *
- * Linux driver for IBM PCI tokenring cards based on the Pit/Pit-Phy/Olympic
- * chipset.
- *
- * Base Driver Skeleton:
- * Written 1993-94 by Donald Becker.
- *
- * Copyright 1993 United States Government as represented by the
- * Director, National Security Agency.
- *
- * Thanks to Erik De Cock, Adrian Bridgett and Frank Fiene for their
- * assistance and perserverance with the testing of this driver.
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * 4/27/99 - Alpha Release 0.1.0
- * First release to the public
- *
- * 6/8/99 - Official Release 0.2.0
- * Merged into the kernel code
- * 8/18/99 - Updated driver for 2.3.13 kernel to use new pci
- * resource. Driver also reports the card name returned by
- * the pci resource.
- * 1/11/00 - Added spinlocks for smp
- * 2/23/00 - Updated to dev_kfree_irq
- * 3/10/00 - Fixed FDX enable which triggered other bugs also
- * squashed.
- * 5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.
- * The odd thing about the changes is that the fix for
- * endian issues with the big-endian data in the arb, asb...
- * was to always swab() the bytes, no matter what CPU.
- * That's because the read[wl]() functions always swap the
- * bytes on the way in on PPC.
- * Fixing the hardware descriptors was another matter,
- * because they weren't going through read[wl](), there all
- * the results had to be in memory in le32 values. kdaaker
- *
- * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
- *
- * 03/09/01 - Add new pci api, dev_base_lock, general clean up.
- *
- * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
- * Change proc_fs behaviour, now one entry per adapter.
- *
- * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
- * adapter when live does not take the system down with it.
- *
- * 06/02/01 - Clean up, copy skb for small packets
- *
- * 06/22/01 - Add EISR error handling routines
- *
- * 07/19/01 - Improve bad LAA reporting, strip out freemem
- * into a separate function, its called from 3
- * different places now.
- * 02/09/02 - Replaced sleep_on.
- * 03/01/02 - Replace access to several registers from 32 bit to
- * 16 bit. Fixes alignment errors on PPC 64 bit machines.
- * Thanks to Al Trautman for this one.
- * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
- * silently ignored until the error checking code
- * went into version 1.0.0
- * 06/04/02 - Add correct start up sequence for the cardbus adapters.
- * Required for strict compliance with pci power mgmt specs.
- * To Do:
- *
- * Wake on lan
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).
