[PATCH 1/3] board: mediatek: fix mmc_get_boot_dev() for platforms without external SD

[David Woodhouse]

On the UniElec U7623 board there is no external SD slot and the preloader
doesn't fill in the magic field at 0x81dffff0 to indicate that it was
booted from eMMC.

Rather than hard-coding it to the Banana Pi R2.

[PATCH 3/3] board: mediatek: Add support for UniElec U7623 board

[David Woodhouse]

This is an MT7623A-based board, very similar to the Banana Pi R2.
