[Qemu-devel] [PATCH v4 00/20] SDCard: bugfixes, support UHS-I (part 5)

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Some refactors, few bugfixes, better SD/SPI support.

With this series apply, machines can use SD cards in UHS-I mode.
(mostly imported from Alistair Francis work)

MMC mode split out for another series,
so UHS enabled MMC cards are still not usable:

  kernel: mmc0: SDHCI controller on PCI [0000:00:05.0] using ADMA
  kernel: sd 0:0:0:0: Attached scsi generic sg0 type 0
  kernel: mmc0: Skipping voltage switch
  [mmc kthread looping]

Since v3:
- simpler SPI handling, improved descriptions (Alistair review)
- inverted patches 16/17 order

Since v2:
- split again in 2... other part is cleanup/tracing

Since v1:
- rewrote mostly all patches to keep it simpler.
