BBB u-boot

[Chris Johns]

The boot time has dropped by 7 or 8 seconds so the average test time has dropped
to 7.1sec letting all tests taking just over 1hr which is nice.

The results are:

Passed:        545
Failed:          7
User Input:      4
Expected Fail:   0
Indeterminate:   0

It seems like minimum is not being handled correctly yet.

Thanks to zmatt on #beagle IRC for some help with the u-boot config.
