SCP firmware for Allwinner sunxi boards

 Some System on a Chip (SoC) computers, also known as single-board,
 embed a dedicated processor called a System Control Processor (SCP)
 which abstracts power and system management tasks away from
 application processors.
 .
 Crust replaces the proprietary firmware on the Allwinner's AR100 SCP,
 found in sunxi boards like Banana/Orange/Lichee Pi or Pinebook/phone.
 .
 There is usually no need to install this package. The same contents
 are more conveniently available from the u-boot-sunxi package.
