Hi Martin, Wen.
Sorry.. Reading my post I did not make it clear.
SD / USB Boot works well under a full UEFI Bios on Baytrail - I.
As Martin says it's not in Seabios yet for Baytrail - I.
But I am sure an updated patch will be coming very soon.

Wen,
I'll push a patch for the muxing - I'd been meaning to do this and just got behind.
I don't believe that SeaBIOS yet supports boot from SD (without a USB translator). Sage pushed a preliminary patch supporting SD boot on specific platforms to the SeaBIOS mailing list a while back, but I don't believe that worked on Bay Trail, and I don't believe that any additional work has been done on the patches since then.
The thread starts here:

Here's a link to the patch:

Hi Julien,
Were those boards using Bay Trail and booting coreboot / SeaBIOS?
I'm assuming you just meant that SD boot works in general.
