Joel and Rohini,
I will have to take some time to catch up.. I apologize that I have not
been able to keep up with the Raspberry Pi work lately, I have just been
too busy with my work projects. ( which is usually a good thing :)

Hi,
I would have to register the related mailbox interrupt and associate it
with a handler that should be same as
_SMP_Inter_processor_interrupt_handler(). Am I right?
From where can I get a reference of how to do this?

That sounds correct.

There is no documentation or information from forums I can find to get a
lead. I suppose i will go ahead with mailboxes. Each core has 4 mailboxes,
usage being left to us. One of the mailboxes can be used here.

They may be and I am seeing references to ARM's own mpcore which uses the GIC.
This appears to be SOC specific but ARM has recommendations which

You should run the SMP tests like all the other tests.
RTEMS kernel image runs fine, but the smp01 executable that I tried

Did you change configure, or configure.ac?
After you change configure.ac or Makefile.am files, you need to run
sb-bootstrap again.
