With the previous implementation, rebooting without registering a recognized reboot mode would end up with U-Boot checking for a valid power-on reason, which might result in the device turning off (e.g. with no USB cable attached and no buttons pressed).
Since this approach is not viable (breaks reboot in most cases), the validity of the reboot reason is checked (in turn, by checking that a warm reset happened, as there is no magic) to detect a reboot and the 'o' char is recognized to indicate that power-off is required. Still, that might be overridden by the detection of usual power-on reasons, on purpose.

... but since Sniper and KC1 are doing the same thing, and other OMAP devices that are also Android devices will also be in the same camp, can we perhaps include some of the above information in a comment, make android_omap_reboot_mode (or something along those lines) in arch/arm/cpu/armv7/omap-common/something-appropriate.c ?
