New Revision: 1323
Added:
trunk/src/target/u-boot/patches/early-powerdown.patch
Log:
board/neo1973/neo1973.c (board_init): power down immediately if we haven't been woken up by the power button or the RTC. This can be overridden by pressing
AUX, i.e., to allow resets to succeed.
Experimental ! Note that this change means that the phone has to be powered up
manually in order to fast-charge when a charger is connected.
