Besides the new value in the version register, this provides:
- ILR support, which includes:
- IDR becoming a pure CPU bitmap, allowing 32 CPUs
- machine check output support (though other parts of QEMU need to...

openpic: remove irq_out

The current openpic emulation contains half-ready code for bypass mode.
Remove it, so that when someone wants to finish it they can start from a

openpic: convert to qdev

This patch converts the OpenPIC device to qdev. Along the way it
renames the "openpic" target to "raven" and the "mpic" target to
"fsl_mpic_20", to better reflect the actual models they implement.

This way we have a generic OpenPIC device now that can handle...

openpic: combine mpic and openpic irq raise functions

The IRQ raise mechanisms of the OpenPIC and MPIC controllers is identical,

Rename target_phys_addr_t to hwaddr

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,...

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...
