More initial RMI files. Note that these so far do NOT compile and many of them may disappear. For example the xlr_boot1_console.c is old code that is ifdef'd out. I will clean these sorts of things up as I make progress on the port. So far the only thing I have I think straightened out is the bits around the interupt handling... and hey that may be broke ;-)

To prevent a LOR we need to pass in a lock flag in the pic routines. In some places we hold the pic lock, others we do not.

Make compilable.. i.e. the FreeBSD id I added must be in comments.

ok we now get so that the uart init's and we can print. We cannot set baud rate as they did in 6.4, this hoses things and we loose our 38400 default term. We now lock somewhere in tcinit.

More initial RMI files. Note that these so far do NOT compile and many of them may disappear. For example the xlr_boot1_console.c is old code that is ifdef'd out. I will clean these sorts of things up as I make progress on the port. So far the only thing I have I think straightened out is the bits around the interupt handling... and hey that may be broke ;-)

To prevent a LOR we need to pass in a lock flag in the pic routines. In some places we hold the pic lock, others we do not.

ok we now get so that the uart init's and we can print. We cannot set baud rate as they did in 6.4, this hoses things and we loose our 38400 default term. We now lock somewhere in tcinit.
