Log:
Remove the mcd(4) driver for Mitsumi CD-ROM players.
This is a driver for a pre-ATAPI ISA CD-ROM adapter. As noted in
the manpage, this driver is only useful as a backend to cdcontrol to
play audio CDs since it doesn't use DMA, so its data performance is
"abysmal" (and that was true in the mid 90's).
No one stepped up to test patches for it either when I last posted patches to
convert it from timeout(9) to callout(9). I have a few more drivers that are
both very old and that people have no business using in 12 (think ISA
adapters that don't do DMA and can't be used with pccard) that I will be
removing over the next little while. I brought up a list of drivers on arch@
a couple of years ago and the conversation drifted off into the weeds about
trimming GENERIC, etc. No one objected to the specific drivers I listed
though (and I got a few pleas of "please remove"). If someone shows up
desperately clutching an ISA adapter they can always dig up the source from
svn and deal with forward porting it for whatever API changes have happened
since it was removed.
I would imagine any machine still holding one of these probably has
not enough memory to run FreeBSD.
would we still run in 2MB?
