I already had this patch in the gru-kevin branch because it solves a
hang in the coreboot -> depthcharge -> U-Boot -> Linux-on-USB chain,
thanks for the pointer though :)

This problem I'm seeing now appears to be something else, but I have no
idea as to what it could be. Since that chain works I assume I should
look more into what coreboot/depthcharge does...
