Does SeaBIOS support eMMC?

[Scheithauer, Mario]

Hello Together,

I play with coreboot and SeaBIOS on a BayTrail platform. We have an 8GB eMMC flash on the board.
With that combination I can boot a Lubuntu.
It seems that the current version of SeaBIOS does not support High-speed eMMC.
Could someone say something about that?
Are there some activities to expand sdcard.c for eMMC bus initialisation?

I would be grateful for any information.

Thanks,
Mario
