Subject: [PATCH] common: add command power off - to switch off the device by
command
This change introduces new config:
- CONFIG_CMD_POWEROFF - which enables cmd/poweroff.c
This requires implementation of function board_poweroff() which
is yet declared in include/common.h
Implementation of board_poweroff() should:
1.a. turn off the device
or
1.b. print info to user about turn off ability
2. never back to caller
Usage is simple: "power off"
Changed for v2016.03:
- Relocated from common directory to cmd directory
- Renamed from cmd_poweroff to poweroff
