state of SMP on daystar quad-604 board

[Taylor Holliday]

Hello again

	That patch improved the situ - I now see 4 penguins - unfortunately the
machine stalls right where INIT should load (???) - no kernel panic - the
cursor just sits there blinking. I played around with smp_software_tb_sync
(commenting it out, etc.) as suggested, it didn't seem to help. So how do I
start remote-debugging this beast? Is there ANY documentation for these quad
boards? Let me know if there's any way I can help.

thanks
- Taylor

There are 2 different things:

 - The old Apple/Daystar 2 CPUs cards. Those should work
 - The old but slightly newer Daystar 2 and 4 CPUs card (using a different
   mecanism from the previous ones). For those I added support, but the
   current _2_4 code is slightly bogus.

First, apply this patch:

.....

Also, if you have >2 CPUs, you may have to comment out the software TB
sync code, I've been told it didn't work with more than 2 CPUs.

We are working on a fix.
