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.
