hw/arm_gic: Remove NVIC ifdefs from gic_state struct

Remove some NVIC ifdefs from the gic_state struct and its
state save/load functions. This means there are some fields
in it which are present for the NVIC but not used, but means
it always has the same layout and can be pulled out into a...

ARM: Exynos4210 IRQ: Introduce new IRQ gate functionality.

New IRQ gate consists of n_in input qdev gpio lines and one
output sysbus IRQ line. The output IRQ level is formed as OR
between all gpio inputs.

qdev: Convert busses to QEMU Object Model

This is far less interesting than it sounds. We simply add an Object to each
BusState and then register the types appropriately. Most of the interesting
refactoring will follow in the next patches.

Since we're changing fundamental type names (BusInfo -> BusClass), it all needs...

qbus: Make child devices links

Make qbus children show up as link<> properties. There is no stable
addressing for qbus children so we use an unstable naming convention.
