bus memory and I/O space access functions/macros, to be used by
machine-independent code for more sane access to bus resources.
New functions will be added to this set, in the future, as appropriate,
but this is a good starting set. Defines:
bus_{io,mem}_{map,unmap}
bus_{io,mem}_{read,write}_{1,2,4,8}
functions, and several types to go with them.
(soon to be documented on mailing lists; eventually in section 9 manual
pages), most importantly:
(1) support interrupt pin swizzling on non-i386 systems with
PCI-PCI bridges (per PPB spec; done, but meaningless, on i386).
(2) provide pci_{io,mem}_find(), to determine what I/O or memory
space is described by a given PCI configuration space
mapping register.
(3) provide pci_intr_map(), pci_intr_string(), and
pci_intr_{,dis}establish() to manipulate and print info about
PCI interrupts.
(4) make pci functions take as an argument a machine-dependent
cookie, to allow more flexibility in implementation.

eventually go away, implemented as wrappers around
the functions described above.

- getcontext() fills the stack_t portion of the context with an 8k size
stack, 0 flags, and below our current stack pointer. I am not sure where
to set the pointer. Thanks pk [2-2] for noticing that.
Now netscape and java work...
to {mainbus,tc,ioasic}_cd.
Change ioasic config name from "lance " to "lance". Correct for
pmaxes, perhaps not for Alphas.
Boots and runs under load on a 5000/200. Hangs during boot on an ioasic
decstation; pmax autoconfig needs fixing.
Add Decstation-3100 baseboard support (untested).

* Delete pmax-specific functions and declarations from trap.c
* Delete mips-geeneric functions and declaratinos from pmax_trap.c
* Rename the function pointer used to handle hardware interrupts to
"mips_hardware_intr". Define it in trap.c. Change references elsewhere,
including machdep.c.
Verified to boot on a 5000/200.
* Add spl4() and spl5() functions from the Pica port.
* Add MachFPTrap() as an alternate entry point for MachFPInterrupt.
The r4k reports floating-point execptions as a trap, not an interrupt,
and the Pica port uses the name MachFPTrap().
* Add nops to the Mach_spl?() functions and MachFPInterrupt, as required
for the r4k port.
Commit "floppy" interrupt counter for vmstat -i.
always be eight digits.
Copy the kn02 memory-interrupt reporting function to the kn03 (5k/240)
memory-error handler, since the 3MAXPLUS seems to use the same ECC hardware
as the 3MAX.
to mips/include/asm.h.
Until all references to <machine/machAsmDefs.h> in the pmax and
pica tree are changed to use <mips/asm.h> directly, just do
#include <mips/asm.h>, for compatibility.
Update the include-idempotency preprocessor token to match.
References to machAsmDefs in vendor (sprite, 4.4bsd) headers left unchanged,
for historical accuracy.
* Display as much revision info as we can get.
* Fix a race condition that could cause interrupts to be lost.
* Handle `out of mailbox' conditions (much) more gracefully.
* Schedule timeouts more safely.
* Add diagnostic code to (correctly) detect if a CCB times out before its
outgoing mailbox is emptied.
provide r3k and r4k versions of each, and move to sys/arch/mips/include.
Note in comments where each mips-based port should provide
definitions in its own cpu.h after including this file.
opcodes from the Pica port. Per Fogelstrom claims the latter are all
supposedly MIPS-II (r6000) instructions, rather than MIPS-III (R4000),
but we haven't checked to be sure. Are LL/SC really in MIPS-II?

code following the MIPS ELF abi.
* Move the kn01 interrupt handler outside of #ifdef DS5000, to support
3100-only kernels.
* Add #ifdef DS3100 around kn01_enable_intr() to allow configuring
turbochannel-only kernels.
Configuration-time support for specific models of DECstation still needs
more thought/work.

- Yet another sanity check included: initialize unused receive buffers to
zero sender id; and test for sender hardware id of zero in the receiver.
Gives us better error messages in case flaky hardware causes spurious
receive interupts.

the NetBSD-1.1 convention. Change the mainbus `struct confargs'
and the "generic" interrupt-establish method, used by devices that
appear on both a kn01 and TC decstations, to match.
Change the macros in autconf.h accordingly.
Add new device-attach struct cfattach le_tc_ca and struct cfdriver le_cd.
Change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd".
Change "mainbuscd" to "mainbus_cd"
update the old-config to new-config glue used with the 4.4bsd/pmax
SCSI drivers to use new device attach declarations and names for
the "oldscsibus", "tz" and "rz" drivers.
change tc_submatch() to compile with the new device-attach scheme:
the TC bus uses a 'submatch' function which checks device locators
and then calls a match function.
Instead of calling cf->cf_driver->cd_match(), we now need to call
cf->cf_attach->ca_match().
Rename the extern declaration of `tccd' and `ioasiccd' in
src/sys/dev/tc/{tvar.h,ioasicvar.h", respectively, to be
`tc_cd' and `ioasic_cd', to match the 1.1B-style definitions.
only include the relevant code in the probe & attach functions. Still
one probe and one attach function, with #ifdefs, but this is a step
in the right direction and saves a few hundred bytes (ooh, ahh!).

return does not work anymore under gcc-2.7.2. Change such functions
to use __attribute__((__noreturn__)). In addition add appropriate
__attribute__ adornments to printf like functions... This generated
another barrage of compiler warnings in printf bugs that I will
promptly fix.
they're base I/O ports, not really addresses. rather than using those
softc fields directly, assign local variables (asicbase, nicbase) to have
their values, and use those. (consistency, plus better optimization
potential in some cases.)
eventually. rename the probe functions for the various boards to 'find' for
consistency/correctness (but the generic8390 check is still a 'probe').
Add protos for ed_find(), ed_probe_generic8390(), ed_find_WD80x3(),
ed_find_3Com(), and ed_find_Novell(). Fix one minor space nit.
