Are you sure they provide technical documentation sufficent to write
the driver?  The last time I asked, I got a nice document that said
that it implemented the sds standard sd host interface, but didn't
document what that was.  TI and winbond chips datasheets are the same
way.  Prove me wrong.  I'd love it :-)
