From b0d1b85fb25a28a9532eaa9dda064b40a0e25f25 Mon Sep 17 00:00:00 2001

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