[Qemu-devel] [PATCH v2 00/25] SDCard: housekeeping, improve SPI, introduce new Specs

[Philippe Mathieu-Daudé]

Hi,

This series intends to simplify the sdcard device:
- add trace points,
- have a more robust SD mode,
- improve the SPI mode,
- introduce the MMC mode (split for a later series)

3 patches as tagged RFC as I need to fix few XXX comments,
checking back the specs.

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

Regards,

Phil.
