[Qemu-arm] [PATCH 0/8] sdcard: cleanup the SD_SPEC version

[Philippe Mathieu-Daudé]

Hi,

This series adds a 'spec_version' property to the SD Card device,
to allow to limit some commands to specific spec version range
(some firmwares use this feature to detect which spec version the
card implements).

This restore the SSI/SD support of the Stellaris LM3S6965EVB board,
which allow to stress the SD Card code with a nice integration test
(waiting for another series to get merged to add the Avocado test):

    $ qemu-system-arm -M lm3s6965evb -serial stdio \
      -kernel sd_card.bin -sd sdcard.img
