With the previous implementation, rebooting without registering a recognized reboot mode (despite registering the magic) 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).
This was designed to catch reboots that are actually intended to be power-off, something that old Android kernels do, instead of properly turning the device off using the TWL4030.
However, since this approach is not viable (breaks reboot in most cases), the validity of the reboot mode magic is checked 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.

Applied to u-boot/master, thanks!
