Right, will fix.

Hm, I don't know. The partition must actively be switched. I know that
the i.MX6 boot ROM actually loads the image from the boot partition
configured in the eMMC. imx6_esdhc_load_image() relies on the
initialization done by the boot ROM, so if the boot ROM just leaves
the eMMC in the state it is before jumping to barebox then barebox
should automatically load the image from the correct place. I haven't
tested it though.
