* Untangled the Cyclades offsets a little. CY16_RESET and CY_CLEAR_INTRbde1998-11-231-14/+32
| | | | | | | | | were half of their physical offsets for ISA and 1/4 of their physical offsets for PCI, while all other Cyclades offsets were physical/1 for ISA and physical/2 for PCI. Logically wrong macros were used to scale CY16_RESET and CY_CLEAR_INTR to the correct physical offsets. Fixed some style bugs (mostly long lines).
* Cleaned up previous commit, mainly by moving repetitive calculationsbde1998-08-131-8/+3

* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-141-1/+1
| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.
* Changes to add support for the PCI version of the Cyclades Cyclom-Ydg1996-10-131-8/+7

* Implemented a more sophisticated mechanism for finding the chip iobasedg1996-10-041-2/+2

* Rewrite:bde1995-07-051-0/+57
- use pseudo-dma - provide the same features and interface as sio - support multiple boards - fix bugs. Some compile-time configuration constants are set to support higher speeds and Cyclom-16Y's at a 30% relative cost in efficiency. Cyclom-16Y support is untested.
