[PATCH] ppc64: Add driver for BPA interrupt controllers
Add support for the integrated interrupt controller on BPA
CPUs. There is one of those for each SMT thread.
The mapping of interrupt numbers to HW interrupt sources
is described in arch/ppc64/kernel/bpa_iic.h.
This version hardcodes the 'Spider' chip as the secondary
interrupt controller. That is not really generic for the
architecture, but at the moment it is the only secondary
PIC that exists.
A little more work will be needed on this as soon as
we have boards with multiple external interrupt controllers.
