35fddd5117 proxy: linux.py: allow to load u-boot before Linux 
right now u-boot can bring up the PCIe bus such that Linux only requires
a very minimal driver. this new --u-boot flag for linux.py allows to
load u-boot before the Linux kernel to make use of this.
This requires a small hack to inject the booti command into the default
u-boot boot environment.
