[Linaro-validation] Staging failure

http://staging.validation.linaro.org/scheduler/job/35505/log_file

This is a bit odd. It got confused when we were in the u-boot prompt while trying to boot up the android test image. It may be some code flaw, though I can't see what, other than it took 5 minutes to get from reboot to that point. Perhaps this calls for a similar approach to booting test images, i.e. if it fails, try a couple more times. May be an edge case, but would put our reliability way up. Along with that, we may have to up the timeouts for booting, given we might do it 3 times.

Thoughts?
