Issue 411: Add flag that can be set by the kernel to do a "reboot to menu"

Reported by Nikolaus Schaller, Nov 20, 2012

Either write some file to SD.
Or store in the U-boot environment.

Question:
* how can a linux kernel set a variable in the u-boot env?

Has been done.

Do:

fw_setenv "forcemenu" yes
reboot

(needs a config file:
