So how does this compare with Vincent Palatin's version?
(http://patchwork.ozlabs.org/patch/106767/) I'm guessing from
the copyright string that it's a modified version -- it would
be nice to say what the differences are.
...and what the differences to Samsung's version are.
We should probably also cc Kevin on the topic.

It looks like this sdhc implements version 1 of standard SDHC
specification, while ours implements second version. Second version
should be backwards compatible with first, I didn't want to submit it
yet to see if vmstate issue will be resolved or not. And also the whole
QEMU SD emulation scheme needs some refactoring which I've been busy
with for a while now. The biggest issues are that currently we cannot
hot-insert SD card into virtual board interface and we do not take any
advantage of QOM (which is hard until Paolo's and Andrea's patches land
in master).
The one advantage of our SDHCI implementation is that it provides
interface to implement SoC-specific successors of standart SDHCI. I'll
send these patches today (even though I wanted to do a lot more
refactoring with them), Peter, could you please test them to find out if
you can use them instead of your SDHCI implementation?
