consumption by 80% or more compared to an idle device.  On boards without a
PMIC, Crust is also responsible for orderly power-off and power-on of the
device.  For this to work, Crust runs outside the main CPU and DRAM, on a
dedicated always-on microprocessor called a System Control Processor (SCP).
Crust is designed to run on a specific SCP implementation, Allwinner's
