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.
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.
Update TURBOChannel and ioasic interrupt-establish routines to pass on their
device argument as a "void *", since that's how all the pmax interrupt handlers
are declared.
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.
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.
and MAXINE (Decstation 5k/xx), instead of setting them to NULL.
New-config kernels should work on those machines now.
Rename the definition of the struct cfdriver for the IO ASIC from "asiccd"
to "ioasiccd", as the config-file name changed from "asic" to "ioasic".
back to the DECstation. Boots on 3MAX and 3MAXPLUS. The bug-fixes
applied to this driver since it forked off the Decstation code also
seem to fix long-standing DMA problems with the Decstation SCSI driver.
the Dallas-compatible real-time clock. The missing entry caused the offset
to end up in the "priority" field. New-style config now boots cleanly on a
KN02 (3MAX).
turhsturbochannel machines. Lifted wholesale from cgd's Alpha
turbochannel code, with changes that reflect the slightly different
bus topology and `slot' numbering on Decstations.
