From: Peter Crosthwaite <address@hidden>
This series enables QOM super class access and demostrates some usages.
Replaces the save->override->call via FooClass technique, to reduce
some of the boiler plate in recently fully QOMified devices.
Applied the change to ARM CPU, MB CPU and some of Andreas's recently
QOMified i386 devices, all which have the save->override->call issue.
ARMCPU I've done a brief test on and seems to work.
ARM CPU was particularly difficult, as it has 3 layers of heirachy,
where a non-concrete class (TYPE_ARM_CPU) need to super class itself
(to TYPE_CPU). This sees the need for super-classers to specify their
expected base class level. See patches for illustration.
The main future work to the series is to apply the change pattern to
the reset of the tree
Peter Crosthwaite (7):
target-arm/cpu.c: delete un-needed instance/class sizes
qom: Add super class accessor
qdev-core: Introduce DEVICE super class cast macros
qom/cpu: Introduce CPU super class cast macros
target-arm: Remove ARMCPUClass
target-microblaze: Remove MicroblazeCPUClass
i8254: Remove [KVM]PITClass
