I have been trying to get the detailed information from the hardware (silicon 
designer) guy about why he believes support for 4-bit MMC is not there, but I 
have not heard back yet.

As soon as I hear from them - and either understand why 4-bit MMC doesn't 
work, or if the Blackfin docs are incorrect (either is OK outcome) - I will 
let you know.

Thanks
