SubjectNew Amiga Driver

Hi there,

I've written a driver for the Amiga multi-serial ZorroII board "A2232"
that I'd like to see included into the main kernel tree.
This is the driver HPA allocated majors 224 and 225 for.

Greetings,
Enver

+ * This driver is in EXPERIMENTAL state. That means I could not find
+ * someone with five A2232 boards with 35 ports running at 19200 bps
+ * at the same time and test the machine's behaviour.
+ * However, I know that you can performance-tweak this driver (see
+ * the source code).
+ * One thing to consider is the time this driver consumes during the
+ * Amiga's vertical blank interrupt. Everything that is to be done
+ * _IS DONE_ when entering the vertical blank interrupt handler of
+ * this driver.
+ * However, it would be more sane to only do the job for only ONE card
+ * instead of ALL cards at a time; or, more generally, to handle only
+ * SOME ports instead of ALL ports at a time.
+ * However, as long as no-one runs into problems I guess I shouldn't
+ * change the driver as it runs fine for me :) .
+ *
+ * Version history of this file:
+ * 0.4 Resolved licensing issues.
+ * 0.3 Inclusion in the Linux/m68k tree, small fixes.
+ * 0.2 Added documentation, minor typo fixes.
+ * 0.1 Initial release.
+ *
+ * TO DO:
+ * - Handle incoming BREAK events. I guess "Stevens: Advanced
+ * Programming in the UNIX(R) Environment" is a good reference
+ * on what is to be done.
+ * - When installing as a module, don't simply 'printk' text, but
+ * send it to the TTY used by the user.
+ *
+ * THANKS TO:
+ * - Jukka Marin (65EC02 code).
+ * - The other NetBSD developers on whose A2232 driver I had a
+ * pretty close look. However, I didn't copy any code so it
+ * is okay to put my code under the GPL and include it into
+ * Linux.
