- replace opt_kgdb_machdep.h with opt_kgdb.h
- defparam opt_kgdb.h:
KGDB_DEV KGDB_DEVNAME KGDB_DEVADDR KGDB_DEVRATE KGDB_DEVMODE
- move from opt_ddbparam.h to opt_ddb.h:
DDB_FROMCONSOLE DDB_ONPANIC DDB_HISTORY_SIZE DDB_BREAK_CHAR SYMTAB_SPACE
- replace KGDBDEV with KGDB_DEV
- replace KGDBADDR with KGDB_DEVADDR
- replace KGDBMODE with KGDB_DEVMODE
- replace KGDBRATE with KGDB_DEVRATE
- use `9600' instead of `0x2580' for 9600 baud rate
- use correct quotes for options KGDB_DEVNAME="\"com\""
- use correct quotes for options KGDB_DEV="17*256+0"
- remove unnecessary dependancy on Makefile for kgdb_stub.o
- minor whitespace cleanup
This adds the missing wbflush() calls after writing register data.
At same time tidy up several comments and make several KNF changes.
XXX: The z8530 MI driver doesn't support bus_space access to the registers
(lacks a hook for storing a bus space tag, and stores register
addresses directly)
Until other ports catch up (this is the first) we have overlayed
the missing data in the MD structures
If the machine uses a Z85230 ESCC device with deep buffers, we observe
output glitches when printing the zstty{0,1} probe lines when the device
is reset & reprogrammed during startup.
There is no easy 'hook' in the MI Z8530 driver, so we wait for output
buffer to drain before changing the baud rate generator prescaler value.
- Using the prom getenv function determine the correct console port
- Remove old prom function hooks
- Tidy up bootflags (remove upper case names, fixup RB_ASKNAME) as
recommended by Jaromír Doleèek
handler to hook up device interrupts and softc callbacks.

* Fixup the indenting in a few places to conform to NetBSD style
