This is my attempt at reducing the size of powerpc_excp and cleaning
it up a bit. It has two parts:
part I (this series) tackles the big switch statement that runs the
interrupt emulation code. Each interrupt now gets its own callback
function that is kept within QOM. The per-processor code still
registers the interrupts in a similar manner to what is done today and
powerpc_excp replaces its switch statement for a function call.
part II (still WIP: https://github.com/farosas/qemu/commits/powerpc_excp)
tries to make powerpc_excp processor agnostic by removing the excp_model
checks and moving processor-specific interrupt properties to
per-processor QOM classes.
I think it would be nice if we could at the end have separate
interrupts and interrupt model implementations. That way we could
start moving things into well defined per-processor files, CONFIGs,
etc.
(So far tested on x86 emulating P9 and compile-only 32-bit and
linux-user. I still need to gather some command lines for the older
cpus.)
