I'm not familiar with booting from eMMC on Arndale. But for newer eMMC (>= JEDEC 4.3) you have to configure a boot partition and enable access to it in the PARTITION_CONFIG register. The "partconf" subcommand of the mmc command can be used to do it. See also Table 2 in [1]. Then install the boot code to the selected boot partition and try again.
