[Qemu-arm] [PATCH 0/4] handle reparenting of SD cards for rpi2

[Peter Maydell]

These patches are a respin of Clement's work on the
rpi2 sd controller/gpio. They fix the valgrind issue that
I was seeing because we got reparenting of the card wrong.

This patchset adds a new qdev patch which makes the
qdev_set_parent_bus() function do most of the work of
unplugging and replugging if the device was already on
a bus. In particular it calls bus_remove_child() which does
a lot of things that the previous "just call object_unparent"
attempt didn't do.

Comments on whether this makes sense to people welcome.
I'm still kind of hoping we can squeeze this into 2.9;
comments on whether that would be unwise also welcome.

thanks
