Andrii,

Did you face any mmc problem when booting dom0?

After I did some io mappings, I could finally get Linux kernel booting message now. But it seems it still has some problems with mmc0:

mmc0: unrecognised SCR structure version 1
mmc0: error -22 whilst initializing SD card
...

Any ideas?

Cheers,
