108 * 1 MiB reserved for the "ARM Power Firmware": this is ARM
109 * code which is responsible for system suspend. It loads a
110 * piece of ARC code ("arc_power" in the vendor u-boot tree)
111 * into SRAM, executes that and shuts down the (last) ARM core.
112 * The arc_power firmware then checks various wakeup sources
113 * (IR remote receiver, HDMI CEC, WIFI and Bluetooth wakeup or
114 * simply the power key) and re-starts the ARM core once it
115 * detects a wakeup request.
