[Qemu-arm] [PATCH v2 0/7] sdcard: cleanup the SD_SPEC version

[Philippe Mathieu-Daudé]

Since v2:
- heavy documentation improvements
- squashed previous 3+4 "add spec_version property default to v2" for atomicity
- SSI/SD patch downgraded to RFC
- added Alistair R-b tags

v1: http://lists.nongnu.org/archive/html/qemu-devel/2018-06/msg00388.html

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 [v2: does NOT] 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
