[Qemu-devel] [PATCH v2 0/3] hw/sd/pxa2xx_mmci: convert to sysbus and vmstate

[Peter Maydell]

This patchset updates the ancient pxa2xx_mmci device to something
resembling modern standards for devices. In particular it makes
it a proper sysbus device and switches to VMStateDescription structs.

The only change here (apart from a trivial rebase) is that since
I sent the first version, commit 5ec911c30ff433 has updated sd_init()
so you can now call it with an already-attached-to-a-device block
backend. This means that the ugliness in the first version with a
pointer property has gone away and we now have a DEFINE_PROP_DRIVE.

(Question: when should a device use DEFINE_PROP_DRIVE and when should
it use DEFINE_BLOCK_PROPERTIES to get the PROP_DRIVE and some other
stuff? We seem to have examples of both...)

There are clearly further cleanup opportunities for this device,
like making the sd callbacks into sysbus gpio input lines rather
than having an ad-hoc pxa2xx_mmci_handlers() function to set them,
but one thing at a time.

Changes v1->v2:
 * (1/3) use an actual DEFINE_PROP_DRIVE property for the drive
