8260 SCC as Console

8260 SCC as Console

[John Traill]

Does anyone have a patch ( Or is working on one ) to use an SCC as a console ?

If not has anyone looked at which changes are required ? I had a quick scan and it would appear to need modifications in m8260_tty.c and the serial_console_xxx functions in uart.c. Are there any 'gotchas' lurking in there.

Yes.  The linuxppc_2_5 kernel has all of the right pieces.  I have
since made some changes that allow this to be selected as a configuration
option, and the patches are in the pipeline back to the FSM Labs trees.

When using the SCC Console, the driver doesn't support SMC serial
ports due to some configuration conflicts I haven't yet resolved.
So far, I haven't seen hardware that uses an SCC console and SMC serial
ports, which places fixing this rather low on my list.

What board are you working on?  I have a Linux port for the ADS8260.....

Dan,

I should have been more specific - Do you have a patch for the ADS8260 ?

Not really.  We (or at least I) and working in three different source
trees now.  There is the 2.4 tree, the linuxppc_2_5 tree and a "merged"
tree.  I did the ADS8260 in this "merged" tree, so any patch would
include lots more than either of the FSM Labs trees.  Tom Rini is
quickly moving all of this into the 2.4 tree, and it will probably
appear there very soon.

Or appear there quickly in a bit.  I know I've got a final or two, in a week
or two.  Gotta find out when and maybe even study. :)

But yes, it should appear there sooner rather then later.
