Subject[RFC PATCH] fdomain: Resurrect driver
Date
Resurrect previously removed fdomain driver, in modern style.
Initialization is rewritten completely, with support for multiple cards,
no more global state variables.
Most of the code from interrupt handler is moved to a workqueue.

Tested on Adaptec AHA-2920A PCI card. ISA and PCMCIA code is untested as
I don't have the hardware.

+ * Driver for Future Domain TMC-16x0 and TMC-3260 SCSI host adapters
+ * Copyright 2019 Ondrej Zary
+ *
+ * Original driver by
+ * Rickard E. Faith, faith@cs.unc.edu
+ *
+ * Future Domain BIOS versions supported for autodetect:
+ * 2.0, 3.0, 3.2, 3.4 (1.0), 3.5 (2.0), 3.6, 3.61
+ * Chips supported:
+ * TMC-1800, TMC-18C50, TMC-18C30, TMC-36C70
+ * Boards supported:
+ * Future Domain TMC-1650, TMC-1660, TMC-1670, TMC-1680, TMC-1610M/MER/MEX
+ * Future Domain TMC-3260 (PCI)
+ * Quantum ISA-200S, ISA-250MG
+ * Adaptec AHA-2920A (PCI) [BUT *NOT* AHA-2920C -- use aic7xxx instead]
+ * IBM ?
+ *
+ * NOTE:
+ *
+ * The Adaptec AHA-2920C has an Adaptec AIC-7850 chip on it.
+ * Use the aic7xxx driver for this board.
+ *
+ * The Adaptec AHA-2920A has a Future Domain chip on it, so this is the right
+ * driver for that card. Unfortunately, the boxes will probably just say
+ * "2920", so you'll have to look on the card for a Future Domain logo, or a
+ * letter after the 2920.
+ *
+ * If you have a TMC-8xx or TMC-9xx board, then this is not the driver for
+ * your board.
+ *
+ * DESCRIPTION:
+ *
+ * This is the Linux low-level SCSI driver for Future Domain TMC-1660/1680
+ * TMC-1650/1670, and TMC-3260 SCSI host adapters. The 1650 and 1670 have a
+ * 25-pin external connector, whereas the 1660 and 1680 have a SCSI-2 50-pin
+ * high-density external connector. The 1670 and 1680 have floppy disk
+ * controllers built in. The TMC-3260 is a PCI bus card.
+ *
+ * Future Domain's older boards are based on the TMC-1800 chip, and this
+ * driver was originally written for a TMC-1680 board with the TMC-1800 chip.
+ * More recently, boards are being produced with the TMC-18C50 and TMC-18C30
+ * chips.
+ *
+ * Please note that the drive ordering that Future Domain implemented in BIOS
+ * versions 3.4 and 3.5 is the opposite of the order (currently) used by the
+ * rest of the SCSI industry.
