This repeats indefinitely. I'm building U-Boot using the default config for board `odroid` and boot the Odroid from an SD card with firmware (`bl1`, `bl2` and `tzsw`) from Hardkernel's clone of the u-boot repository [1]. There are no peripherals connected apart from the SD card and the serial console. Please let me know if you need more information.
