thorpej 649ff32f2b Rather than using a magic constant, use `com_scratch' as the offset 
in UART space to the interrupt CSR.

jdolecek 2185bcc386 MI part of MicroChannel Architecture bus support 
This work is based on code written by Scott D. Telford, the IBM
Token Ring card attachment was written by Gregory McGarry.

XXX this is still very experimental and development version; use at your
XXX own risk

jhawk e02d0e3597 Back out rev 1.7 of i82365_isa.c; 0x300-0x3ff, or even 0x330-0x3ff 
is not a reasonable place to allocate 12-bit pcmcia iospace.
It seems to cause conflicts on a large number of modern laptops,
necesitating hand-patching of the kernel (mostly due to
video devices in the upper range of that space).

This will presumably cause problems on the NEC Versa 6030X,
however that appears to be a vastly less common case than
the laptops that are inconvenienced by the current state.

12-bit iospace now uses 0x400-0xfff.

mycroft 319d44bfb1 Adjust asm patterns for newer versions of GCC. 2000-05-03 21:20:07 +00:00
thorpej 712326ecbd Traditionally, the floppy controller was configured at 0x3f0 for 8 ports, 
but the registers actually begin at 0x3f2, and this is what PNPBIOS reports
for the floppy controller resources.  Adjust the register offsets and the
mapping of them for the ISA front-end to compensate, so that the PNPBIOS
attachment of the floppy controller actually works.

thorpej 0cde36f780 Carve off the ISA configuration bits from the floppy driver. Driver is 
still ISA-specific, but we can attach ISA instances with different
configuration mechanisms now.

explorer d592132506 the status register is _always_ at 0x420 -- grr. How should I put this in the config file rather than hard-coded? 2000-04-21 20:13:41 +00:00
explorer 1118b3ee75 Add driver for Addonics FlexPort 8S (and probably 4S, but not tested) 2000-04-21 17:48:30 +00:00
thorpej 4044b5a41c Use separate callouts for motor-on and motor-off. Fixes a condition 
where the floppy driver would wedge because a motor-on timeout would
be cancelled by another I/O operation cancelling a motor-off timeout.

thorpej 91d6998394 Combine the Alpha, BeBox, and i386 ISA floppy drivers with a sledgehammer. 
Not a perfect solution, but this is two less versions of this driver I
now have to modify.

thorpej fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

thorpej 42144199a1 - Make the pcppi and pckbd drivers cooperate a little more -- pckbd provides 
a call to hook up a bell-ringer (since the keyboard itself has no bell).
  This eliminates the need for #ifdefs for the bell-ringer in the pckbd
  driver.
- Add cnbell() support to pckbd.
