As per the README.md on the crust github:

Crust improves battery life and thermal performance by implementing a deep sleep state. During deep sleep, the CPU cores, the DRAM controller, and most onboard peripherals are powered down, reducing power consumption by 80% or more compared to an idle 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 AR100.

To build crust manually with uboot you can find instructions Here.
