-/*
- * Created 20 Oct 2004 by Mark Lord
- *
- * Basic support for Delkin/ASKA/Workbit Cardbus CompactFlash adapter
- *
- * Modeled after the 16-bit PCMCIA driver: ide-cs.c
- *
- * This is slightly peculiar, in that it is a PCI driver,
- * but is NOT an IDE PCI driver -- the IDE layer does not directly
- * support hot insertion/removal of PCI interfaces, so this driver
- * is unable to use the IDE PCI interfaces. Instead, it uses the
- * same interfaces as the ide-cs (PCMCIA) driver uses.
- * On the plus side, the driver is also smaller/simpler this way.
- *
- * This file is subject to the terms and conditions of the GNU General Public
- * License. See the file COPYING in the main directory of this archive for
- * more details.

- * No chip documentation has yet been found,
- * so these configuration values were pulled from
- * a running Win98 system using "debug".
- * This gives around 3MByte/second read performance,
- * which is about 2/3 of what the chip is capable of.
- *
- * There is also a 4KByte mmio region on the card,
- * but its purpose has yet to be reverse-engineered.
