This is a collection of random conversions to devices to the new memory API.
Some qemu interfaces are also update, for example machine creation and
sysbus.
Please review. If all is fine, I will post a [PULL] request for the batch
(in git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git memory/batch).
v2:
- removed <glib.h> includes
- folded in a build fix
- dropped patch 6, "QEMUMachine: pass address space to machine init".
unfortunately this scatters a lot of get_system_memory() which will have
to be replaced by something better.
Avi Kivity (22):
stellaris_enet: convert to memory API
sysbus: add helpers to add and delete memory regions to the system
bus
pci_host: convert conf index and data ports to memory API
ReadWriteHandler: remove
an5206: convert to memory API
armv7m: convert to memory API
axis_dev88: convert to memory API (RAM only)
sysbus: add sysbus_add_memory_overlap()
integratorcp: convert to memory API (RAM/flash only)
leon3: convert to memory API
cirrus: wrap memory update in a transaction
piix_pci: wrap memory update in a transaction
Makefile.hw: allow hw/ files to include glib headers
pflash_cfi01/pflash_cfi02: convert to memory API
dummy_m68k: convert to memory API
g364fb: convert to memory API
lm32_boards: convert to memory API
mainstone: convert to memory API
mcf5208: convert to memory API
milkymist-minimac2: convert to memory API
milkymist-softusb: convert to memory API

cfi02 is annoying in that is ignores some address bits; we probably
want explicit support in the memory API for that.

Shirley can't write any code. I'll fix it up.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

This would deserve some reordering to reduce the code under #ifdef.
Anyway, it also breaks the musicpal (and presumably all other flash
users) because memory_region_init_rom_device is broken. It assumes
mr->ops is set, but I guess it rather should set that field itself, no?

Sure, but I try to avoid refactoring in these conversions. We already
have too many regressions.
