This is a common generic PCI SATA controller that is also used in PCs
but more importantly guests running on the Sam460ex board prefer this
card and have a driver for it (unlike for other SATA controllers
already emulated).


looks like this new device can now be used to crash QEMU in certain

$ ppc64-softmmu/qemu-system-ppc64 -monitor stdio
QEMU 2.11.50 monitor - type 'help' for more information
(qemu) device_add sii3112,id=x
(qemu) device_del x
qemu-system-ppc64: /home/thuth/devel/qemu/memory.c:2346:
memory_region_del_subregion: Assertion `subregion->container == mr' failed.
Aborted (core dumped)

Any ideas how to fix this?

Looks like the exit function that causes this crash was left there by mistake and is not needed. I've sent a patch to remove it.

Thank you,
