"New" vs. "Old" Style Interrupts

[Joel Sherrill]

This is a positive comment.  I assume it means you now have ticker
working. :)

Unfortunately, there isn't any. :(  I suspect that the best thing to
do it start with another BSP such as motorola_shared and dissect it
and apply similar changes to the ppcn_60x BSP. 

There are people on the list who have done this to other BSPs. Hopefully
one of them has notes or guidance.

Also be warned that the ppcn_60x BSP is the ONLY RTEMS BSP in or out of
the tree with a driver for the KA9Q TCP/IP network stack.  That driver
needs to be reworked/replaced to work with the BSD stack.  RTEMS used
that stack for a short period of time a few years ago and unfortunately,
this BSP got stuck as the only one never upgraded.
