[FREELDR]
- Effectively reboot instead of exiting the bootloader and hanging. - Do a cold reboot instead of a (soft) warm reboot, to let the user be able to choose another boot support or do anything else, instead of directly rebooting to the bootloader. Rename the concerned function accordingly. svn path=/trunk/; revision=57935
