The Great PC98 Merge. All new code is "#ifdef PC98"ed so this should make no difference to PC/AT (and its clones) users. Ok'd by: core Submitted by: FreeBSD(98) development team
1996-06-14 11:02:28 +00:00
#ifdef PC98
#error isa.h is included from PC-9801 source
#endif
Made all header files idempotent and moved incorrect common data from headers into a related source file. Also fixed a bug in ed_probe() where it was possible to fall off the end of the function
1993-11-07 17:44:34 +00:00
#ifndef _I386_ISA_ISA_H_
Move declarations of atdevbase and rtcin() to cpufunc.h (a less wrong place). Fix spelling error. Uniformize idempotency ifdef.

Convert to ANSI C: change #endif THING to #endif /* THING */. Fix one such THING in code to match comment. Sort IO_GSC* into numeric order and update comments about the gaps. Sort common SCSI addresses into alphabetical order. Remove bogus comments about com ports having i/o size 4. Uniformize whitespace. Uniformize case in hex digits. This file is very incomplete. In particular, it doesn't mention any network cards. This doesn't matter much for the base addresses, but it means that the comments about which addresses are free are mostly bogus. The i/o sizes are unreliable because of split address ranges for many devices (VGA, wd). The i/o sizes are incomplete. In particular, there are no sizes for SCSI controllers. The bt driver still returns a truth value instead of a size.

Remove now obsolete port assignments and sizes. These more properly belong in the respective drivers. I've not removed ALL of them, as a few still haven't moved. I've just removed the ones that aren't used. # these can be removed from amd64, but I'm having issues getting to # sledge at the moment for a build.
