Ah, I thought ePAPR listed mmc already. Using "sdhci" is a little too
specific here, since a lot of mmc hosts are not sdhci compliant, and
"sdhc" is completely wrong, because that identifies a specific card
type, but a host that supports SDHC cards will generally also work
with SD (less than 4GB) or SDXC (more than 48GB) cards.
