jonathan f5343d2229 Cleanups, and convergence with the Alpha driver:
* kill scc_tty[] and needs-count.
  * Add usable-when-cold version of sccparam().
  * Add pre-autconf() console initialization entrypoint.
  * remove lint for gcc -Wall
  * wbflush() -> tc_mb()
all but the last of which have been fed through cgd and committed to the
Alpha scc driver.

mhitch b7ef581afb The MAXINE serial console is on scc0 (the only SCC on the MAXINE) instead
of scc1.  Fix the check of which scc to initialize the console serial line
so that the MAXINE serial console will work.

mycroft b3eac79b64 tty stop functions really should return void, not int, and certainly not both. 1996-09-02 06:43:16 +00:00
mhitch 56a2e98b80 Do tty_attach() for serial lines. 1996-06-16 16:49:07 +00:00
mhitch fe55416706 Fix autoconfiguration stuff to more closely match the alpha - primarily
the IOASIC attached devices.  The DS3100 will now configure properly.
Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts
get enabled.
Fix up a moved include file.

jonathan f7af868d1f Additional fixes to complete the NetBSD/1.1B config changes:
change IOASIC cfdriver references  from "ioasiccd" to "ioasic_cd"

thorpej 77abd102b7 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

jonathan b5c68cb4cd Add serial-console support that works with `new-style' (config.new) autconf
code.  Substantially the same code tested on a 5k/240. Should work on a
5k/1xx.  Not tested on a  MAXINE, where the single unit may break the
PROM-channel-number to driver-channel-number mapping.

jonathan e229c8d175 Resolve pmax and alpha IOCTL asic driver differences, pass 1:
Rename the ioctl asic register and slot macros from ASIC_<xxx> to
IOASIC_<xxx>, to be compatible with the machine-indpendent names in
sys/dev/tc/ioasicvar.h.  The pmax code still uses
sys/arch/pmax/pmax/asic.h, as some of the registers and offsets
defined there are not yet defined in sys/dev/tc/ioasicvar.h.

Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'.

jonathan 5ea2ec2357 Re-write Decstation turbochannel autoconfiguration code to use the machine-
independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
  * Change the tc autoconfiguration tables to use a struct tc_attach_args
    instead of the ad-hoc structure.
  * Change all pmax device drivers to use a `struct confargs' that's
    assignment-compatible with  sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
    Devices that can be present on a TC or as ioctl asic/mainbus builtins
    use  the same `struct confargs'.
  * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
    an old, now-obsolete sys/arch/alpha snapshot.

  * Update the comments and debugging code in interrupt handlers to
    be consistent with the machine-independent TC support.

Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.

jonathan 8945da0c58 Add speed entries for 7200 and multiples.
Add as-yet-unused speed entries for a 1x SCC clock, up to 200 Kbits.

Remove old top-bit-means-delay code, since nothing seems to need it,
and it apparently partially broke lk-201 initialization anyway.

jonathan f28ebc66ca Fix SCC bug that broke getty on pmax SCC lines: if RAW and LITOUT were
both off, haracters with their top bit clear were interpreted as a delay.
This (strange) behaviour is still available if  SCC_PARITY_MEANS_DELAY
is defined.

jonathan 27361456c5 Force a delay after calling SCC_WRITE_DATA() to give the chip
registers time to settle. DELAY(2) is reportedly enough.  Without the
delay, output characters are occasionally doubled.

jonathan f8fbfa0ce8 Change pmax rcons and low-level serial drivers to support the
old-style pmax polled input for cn_getc(). Needed because the
input side of rcons is not initialized in time for GENERIC kernels
to use it to read a root/swap devicename from /dev/console.

jonathan 8522bd48f3 Move the pmax scc driver from sys/arch/pmax/dev to sys/arch/pmax/tc,
as it's a driver for a device under a TC IOASIC.   The Alpha port also
has its scc driver in tc/scc.c, and the pmax driver scc is nearly the same
as the Alpha.
