Where CACHED_TO_HYS() is still needed for kernel-virtual-to-physical
or physical-to-uncached mapping (fb drivers), replace with
`#include <mips/cpuregs.h>'.
* dcparam() with normal tty t_param interface, which calls
* cold_dcparam() called with explicit dc7085 register address
and flags, which does the work and is also callable when cold,
to set up console (or kgdb) line parameters.

use the pre-autoconfig cold serial-console inititialization entry
points from the bus-specific cfattach front-end code.
* Delete post-autoconfig code to switch from PROM output to kernel
driver for machines with dc serial chips.
cfattach front-end code:
dc_ds for the decstation 2100( pmin), 3100 (pmax), and 5100.
dc_ioasic for the decstation 5000/200 (3max) which does not have a
DEC TC-style IOCTL asic, but is configured as if it did.
* Add pre-autoconfig code initialization of kerenl dc driver console I/O
for remote serial consoles. The hack to use PROM serial I/O until the
dc device is autoconfigured is no longer necessary.
serial consoles to the 1.2 branch. Includes:
* dynamically allocated new-config softc
* remove dependencies on Decstation CPU type, use flags in softc instead.
* pass in values for softc flags (q.v.) from parent-specific attach code
* #ifdef out rts/cts flow control support until it's known to work on
200s.
* redo initialization of serial consoles (needs more work).
The Lite2 changes include:
* Remove the last vestiges of high-bit-set-means-delay for output chars.
* Handle the 2100/3100 having partial modem control on line 2 only,
whereas the 5000/200 has modem control signals on lines 2 and 3.
* Add RTS/CTS support for lines 2 and 3 on a 5000/200.
* Add more s = spltty(); splx(s); where needed but not present.
as a console, initalize as white-on-black so console messages are legible.
(Sean Davidson reports that rcons still messes up the display, perhaps
due to using the wrong pixel depth).
1. Start at the specified entry instead of entry 0.
2. Use the blue value instead of the green when setting the blue color entry.
3. Don't use the starting index again for storing the saved entry - the cmap
pointer was previously initialized using the starting index. This fixes
a hard hang on the maxine when console output is done after calls to
set the color map (usually by the X server).
* Add interrupt handler for 3MIN, where we cannot disable TC slot interrupts.
* Change mfbinit() signature to match other (pmax) TC framebuffer init
routines.
* TODO after 1.2: add {cfb,mbf,sfb}var.h. Declare init functions there.
message-in. The remaining transfer count restored when a device is
reselected needs to be saved. The saved value is needed to compute
the number of bytes transferred if another disconnect occurs. This
fixes a random read data corruption that occurs on certain disks that
may disconnect more than once in the middle of a DMA transfer.
Show proper inquiry data when version >= 1, not <= 1 (SCSI-2 devices
now display their inquiry infor).
Correct transfer length passed to dk_unbusy (b_resid hasn't been
updated yet).
configure properly. Also fix devices with TurboChannel and mainbus
attachments so they will work if no TurboChannel was configured.
Fix clock.c for a missing variable if not including NTP support.
Also remove some extraneous includes files or use the right ones.
configure properly. Also fix devices with TurboChannel and mainbus
attachments so they will work if no TurboChannel was configured.
Fix a panic when the dtop keyboard handler receieves a character
before the device has been opened.
update the 4.3bsd/Ultrix-compatible qvss-style mmap'ed framebuffer/input-event
code to use mips_round_page() et.al., not pmax_round_page().
Add explicit "int" return types to functions. Add prototyped forward
declarations.
Fix the the definitions of dtop cdevsw entry point functions to match
their declarations. Add explicit "int" declarations to functions.
Add prototyped declarations for all local functions.
Return zero from dtopstop().
Include the external declarations from dtopvar.h.
