mjacob 019508faee Well, I don't have a Cyclades board, but I needed the alpha kernels
to compile. I made the changes that seemed to make sense tracking the
shift from TS_WOPEN  to tp->t_wopen- but they may be wrong. I wasn't
subscribed to tech-kern so I missed the discussion, and C. Hannum
was not particularly enlightening. Sorry if this isn't quite right.

cgd 57f46a9e4a fix several bugs pointed out by Jarkko Torppa <torppa@cute.fi> in PR 3753:
(1) fix a printf format (%x to print int, not %lx).
(2) fix probe of 4th chip/16th channel (used to tell whether or not the
    board is a 16- or 32-port board) by removing an incorrect offset so
    that the code matched its comments. (!!!)
(3) fix storage of chip number in per-channel structure so that it actually
    stores the chip number, rather than the chip offset.  This allows the
    driver to work with more than the first four channels (i.e. with chips
    other than chip number 0, which happens to have an offset of zero). (!!!)

cgd 04e7505aaa clean up an autoconfiguration printf. Much more should be done 1997-04-13 20:00:29 +00:00
thorpej 16c4c5af26 New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.
