* linux/drivers/sbus/char/aurora.h -- Aurora multiport driver
*
* Copyright (c) 1999 by Oliver Aldulea (oli@bv.ro)
*
* This code is based on the RISCom/8 multiport serial driver written
* by Dmitry Gorodchanin (pgmdsg@ibi.com), based on the Linux serial
* driver, written by Linus Torvalds, Theodore T'so and others.
* The Aurora multiport programming info was obtained mainly from the
* Cirrus Logic CD180 documentation (available on the web), and by
* doing heavy tests on the board. Many thanks to Eddie C. Dost for the
* help on the sbus interface.

*
* Revision 1.0
*
* This is the first public release.
*
* This version needs a lot of feedback. This is the version that works
* with _my_ board. My board is model 1600se, revision '@(#)1600se.fth
* 1.2 3/28/95 1'. The driver might work with your board, but I do not
* guarantee it. If you have _any_ type of board, I need to know if the
* driver works or not, I need to know exactly your board parameters
* (get them with 'cd /proc/openprom/iommu/sbus/sio16/; ls *; cat *')
* Also, I need your board revision code, which is written on the board.
* Send me the output of my driver too (it outputs through klogd).
*
* If the driver does not work, you can try enabling the debug options
* to see what's wrong or what should be done.
*
* I'm sorry about the alignment of the code. It was written in a
* 128x48 environment.
*
* I must say that I do not like Aurora Technologies' policy. I asked
* them to help me do this driver faster, but they ended by something
* like "don't call us, we'll call you", and I never heard anything
* from them. They told me "knowing the way the board works, I don't
* doubt you and others on the net will make the driver."
* The truth about this board is that it has nothing intelligent on it.
* If you want to say to somebody what kind of board you have, say that
* it uses Cirrus Logic processors (CD180). The power of the board is
* in those two chips. The rest of the board is the interface to the
* sbus and to the peripherals. Still, they did something smart: they
* reversed DTR and RTS to make on-board automatic hardware flow
* control usable.
* Thanks to Aurora Technologies for wasting my time, nerves and money.

* activated by the on-board chip, and if the board has RTS and DTR swapped,
* this facility is usable. The second case is when the application is so
