Hi,

I'm trying to make "ppcoea-renovation"  NetBSD/sandpoint  compiled and
has hit hard against a puzzle of how to update sandpoint/extintr.c.  My intent
is to port NetBSD/sandpoint to one of MPC8245 eval brds, in specific Ampro
EnCorePP1.  MPC8245 has built-in interrupt controller named EPIC
which is supposedly to replace OPENPIC found in sandpoint brds.  The
file is an essential to implement right interrupt steering and handling.
The eval's PDF is available;
    http://www.alkyltechnology.com/files/EnCPP1RefMan.pdf
Figure 4-2 of page 49 depicts the interrupt structure between EPIC and an
external interrupt source from VIA686B South bridge.  How can I adapt
proposed common interrupt scheme to MPC8245 EPIC?
