+ * this driver has been hacked by Matteo Frigo (athena@theory.lcs.mit.edu)
+ * to support EPP and scatter-gather.                        [0.26-athena]
+ *
+ * additional hacks by David Campbell
+ * in response to this driver "mis-behaving" on his machine.
+ *      Fixed EPP to handle "software" changing of EPP port data direction.
+ *      Chased down EPP timeouts
+ *      Made this driver "kernel version friendly"           [0.28-athena]
+ *
+ * [ Stuff removed ]
+ *
+ * Corrected ppa.h for 2.1.x kernels (>=2.1.85)
+ * Modified "Nat Semi Kludge" for extended chipsets
+ *                                                      [1.41]
+ *
+ * Fixed id_probe for EPP 1.9 chipsets (misdetected as EPP 1.7)
+ *                                                      [1.42]
+ *
+ * Development solely for 2.1.x kernels from now on!
+ *                                                      [2.00]
+ *
+ * Hack and slash at the init code (EPP device check routine)
+ * Added INSANE option.
+ *                                                      [2.01]
+ *
+ * Patch applied to sync against the 2.1.x kernel code
+ * Included qboot_zip.sh
+ *                                                      [2.02]
+ *
+ * Cleaned up the mess left by someone else trying to fix the
+ * asm section to keep egcc happy. The asm section no longer
+ * exists, the nibble code is *almost* as fast as the asm code
+ * providing it is compiled with egcc.
+ *
+ * Other clean ups include the follow changes:
+ *    CONFIG_SCSI_PPA_HAVE_PEDANTIC => CONFIG_SCSI_IZIP_EPP16
+ *    added CONFIG_SCSI_IZIP_SLOW_CTR option
+ *                                                      [2.03]
+ *
+ * Use ppa_wait() to check for ready AND connected status bits
+ * Add ppa_wait() calls to ppa_completion()
+ *  by Peter Cherriman <pjc@ecs.soton.ac.uk> and
+ *     Tim Waugh <twaugh@redhat.com>
+ *							[2.04]
+ *
+ * Fix kernel panic on scsi timeout, 2000-08-18		[2.05]
+ *
+ * Avoid io_request_lock problems.
+ * John Cavan <johncavan@home.com>			[2.06]
+ *
+ * Busy wait for connected status bit in ppa_completion()
+ *  in order to cope with some hardware that has this bit low
+ *  for short periods of time.
+ * Add udelay() to ppa_select()
+ *  by Peter Cherriman <pjc@ecs.soton.ac.uk> and
+ *     Oleg Makarenko <omakarenko@cyberplat.ru>         
+ *                                                      [2.07]
