i386ex -> custom 386sx bsp

- Subject: i386ex -> custom 386sx bsp
I am trying to adapt the i386ex bsp to run on a special 386sx board which
currently has no serial port. I am using printk instead of printf and
directing the printk strings to dual port memory from which the strings can
be viewed with a debugger on another processor on the same board. First I
got the hello program to work. Now I am working on the ticker program. The
ticker program prints the initial time in the 3 tasks one time and then
stops. I don't think my timer interrupt is working. Also, I see a couple
of times the message "raw_idt_notify has been called." I think this means
an interrupt is occurring with no handler. I would think I should never get
this message. Is this true?
Also, if I understand the i386ex bsp, the timer interrupt should connect to
IR0. Is this true?
I am working with the code from rtems-4.0.0.
Any comments or help would be most appreciated.
