SD Card , SD Card Boot work. We have designed several Boards with SD Card Boot.
Although I would recommend USB3 Boot as it's a magnitude faster.

Subject: [coreboot] Baytrail SD card interface

Hello all,

Does the current baytrail fsp coreboot code support SD/uSD card interface?
Is anybody able to get it to work on Bayley Bay CRB? It does not seem to work on our CRB. We checked the SD3_PWREN signal, it always remains high and therefore the SD card doesn't get any power.
