+/*
+ *  linux/drivers/ide/pci/delkin_cb.c
+ *
+ *  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.

+ * There is also a 4KByte mmio region on the card,
+ * but its purpose has yet to be reverse-engineered.
