Geo,
The MMC driver in uBoot seems to have problem with some SD cards. Might be the timing setings was too short and it's timed out too quickly.
Exactly what point did the block read error occurred? Did you mean during loading either one of the images? But once both were loaded, then it is OK? Do you still have the log or can recreate it?
I'll need to rebuild Davy's uBoot image if we want to make it more resilient. So far I've built a version with his USB patch only and it worked fine. I have not tried to add MMC yet.
