Abstract
A system for performing coincident boot of computing devices having non-volatile memory and secure and non-secure partitions on the same System on Chip (SoC) or on a similarly capable computing device with secure division and separation of sensitive memory resources, secure protection of intellectual property during boot and post-boot, and support for secure interoperations between secure and non-secure states. The system packages components of the boot loader into a single signed and encrypted package. That package is loaded into the non-secure memory where it is verified before being extracted to the secure partition.
