[RFC PATCH 00/10] hw/sd: Start splitting SD vs SPI protocols

[Philippe Mathieu-Daudé]

Hi Cédric,

After our discussion yesterday about how to add support for MMC
(and eMMC) I looked at how to easily add these bus protocols,
which might have commands quite different, avoiding to have big
unreadable if/else statements.

I'm not yet happy enough with the result but it is a starting
point which keeps things still simple.
What I'm wondering is if we could include the command classes
(as another dimension in the array). Also if we could use the
older spec version supported as base set of commands, and if the
user asks for more recent spec version, for each version we
overwrite the array of commands. Thoughts?

Phil.
