The isa attachment code is in isa/lpt_isa.c now, which attaches to the
already created ic/lpt* files.
You don't need to change your config files, but you need to re-"config" if
using lpt at isa.
XXX The "lpt" device definition should be in sys/conf/files instead, but to
my knowledge, there are some ports which have private copies of lpt, and would
choke on that. No need to make people unhappy 7 days before release branching.
pseudo-device rnd # /dev/random and in-kernel generator
in config files.
o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
[1] add EN_ENIDMAFIX - the byte-aligner on the ENI version of the card
appears to lose under heavy load so avoid using it. see comment
in midway.c for full details.
note that the Adaptec version of the card works properly under
load.

fix by chuck & kjc
[2] update some freebsd specific code [from kjc]
[3] for circular buffers: ensure there is always one free slot so
that we can easily tell the difference between a full and
empty list. re-structure a few loops to reflect this.
fixes a problem with mbufs being free'd while still in DMA,
and makes drive a bit more robust.

* support chip clocks != COM_FREQ, by introducing sc_frequency (for the
mainline code) and adding a frequency parameter right after the rate
parameter to comcnattach() and com_kgdb_attach().
- Make com_isa and com_multi initialize sc_frequency to COM_FREQ.
- Make i386/machdep.c and alpha/dec_xxx.c call com*attach() with the freq.
parameter.
* supio_attach_args get two more fields: a sc_ipl and a sc_arg, both ints.
- com_supio uses the first for interupt establishment (all childs will, as
soon as they exist) and the 2nd for sc_frequency.
- drsupio passes sc_ipl alway as 5, and for the "com"s, sc_arg as 16*115200
- hyper will pass sc_ipl as 6, and sc_arg as 16 * 460800
be probed several times. This fixes the "ATAPI CD probed as wd drive" problem.
Thanks to Geoff Wing <mason@primenet.com.au> for testing this on his hardware.
I also made inclusion of LPRINTF() dependent solely on the symbol
LPTDEBUG, initialized lptdebug variable to 0 instead of 1, and
matched arguments to format strings in LPRINTF() calls.
