[Qemu-devel] [RFC][PATCH 0/4] Add support for SDHCI PCI devices

[Kevin O'Connor <kevin@koconnor.net>]

I'd like to be able to emulate SD cards on x86 machines for testing
purposes.  I put together a patch series to modify the existing SDHCI
code so that it can also be used as a PCI device, and can thus be used
on any PCI platform (such as x86).

Vincent Palatin had patches to do this a couple of years ago, but his
patches no longer apply to the current qemu tree.  See:
  https://lists.nongnu.org/archive/html/qemu-devel/2011-07/msg02833.html
This series is not directly based on Vincent's patches, and is instead
mainly based on the sdhci code currently in the qemu tree.

I've lightly tested this series on x86 and confirmed that a standard
linux kernel can find and mount the given device.  To test, I add the
following to the command line: -device sdhci-pci -sd my-drive

Unfortunately, I have not been able to test the existing arm support
(which uses sysbus), but I will test if I can find an available qemu
arm image.

I'm not that familiar with QEMU internals.  Comments welcome.
