c5e30cc02b Last minute TTY API change: remove mutex argument from tty_alloc().
I don't want people to override the mutex when allocating a TTY. It has
to be there, to keep drivers like syscons happy. So I'm creating a
tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex()
should eventually be removed.

The advantage of this approach, is that we can just remove a function,
without breaking the regular API in the future.

44a2eb509f Remove an unused variable to make the SENTRY5 mips kernel compile
(though with some asm warning).

c8978106d0 Remove unused consdev structure fields.
The cn_unit and cn_tp fields don't seem to be used anywhere. Some
drivers set them, while others don't. Just remove them, in an attempt to
make our consdev code a little easier to understand.

750595ef63 Change while (cond)\n\t\t; to while (cond)\n\t\tcontinue; since the
former more explicitly tells the compiler that you want an empty loop.
There are some lint programs that use this hint to avoid generating
warnings.

No functional change...

6f079ba163 Catch up to latest tty, kdb and SYSINIT changes. Modeled after the
dev/ofw changes, since this driver appears to have used that as a
start years ago...

8e8ee9aaba The Ultra2 never had a CFE console or CFE boot loader. Kill obvious
cut-n-paste leftover.

ae36cccd6e Support for CFE boot loaders. Initially the support is for MIPS, but
other processors will work too.
