Unfortunately, it turns out that rootwait/delay doesn't help. The problem
occurs even earlier: U-Boot cannot find any bootable devices. Therefore, I
need to add a delay in U-Boot.
But it is not a big deal - I very rarely power-cycle my Wandboard. It is on a
UPS, and runs 24/7. It is only power-cycled if I have to replace hardware.
