2016-02-18hw/sd/sdhci.c: Update to use SDBus APIsPeter Maydell
Update the SDHCI code to use the new SDBus APIs. This commit introduces the new command line options required to connect a disk to sdhci-pci: -device sdhci-pci -drive id=mydrive,[...] -device sd,drive=mydrive Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Alistair Francis <alistair.francis@xilinx.com> Message-id: 1455646193-13238-6-git-send-email-peter.maydell@linaro.org
2016-02-18hw/sd: Add QOM bus which SD cards plug in toPeter Maydell
Add a QOM bus for SD cards to plug in to. Note that since sd_enable() is used only by one board and there only as part of a broken implementation, we do not provide it in the SDBus API (but instead add a warning comment about the old function). Whoever converts OMAP and the nseries boards to QOM will need to either implement the card switch properly or move the enable hack into the OMAP MMC controller model. In the SDBus API, the old-style use of sd_set_cb to register some qemu_irqs for notification of card insertion and write-protect toggling is replaced with methods in the SDBusClass which the card calls on status changes and methods in the SDClass which the controller can call to find out the current status. The query methods will allow us to remove the abuse of the 'register irqs' API by controllers in their reset methods to trigger the card to tell them about the current status again.

2016-02-18hw/sd/sd.c: QOMifyPeter Maydell
Turn the SD card into a QOM device. This conversion only changes the device itself; the various functions which are effectively methods on the device are not touched at this point.

2015-12-22sdhci: add optional quirk property to disable card insertion/removal interruptsAndrew Baumann
This is needed for a quirk of the Raspberry Pi (bcm2835/6) MMC controller, where the card insert bit is documented as unimplemented (always reads zero, doesn't generate interrupts) but is in fact observed on hardware as set at power on, but is cleared (and remains clear) on subsequent controller resets.

2015-12-07sdhci: Sanitize "sdhci-pci" properties for future qomificationMarkus Armbruster
We currently fuse controller and card into a single device model, but we intend qomify things properly and separate the two. The properties that really belong to the card would then have to somehow pass-through to the card's properties. To avoid that complication, either mark them experimental or drop them. Properties "capareg", "maxcurr" and the usual PCI device properties belong to the controller. Property "drive" belongs to the card; rename it to "x-drive". Properties "logical_block_size", "physical_block_size", "min_io_size", "opt_io_size", "discard_granularity" belong to the card, but have no effect; drop them.
