Abstract
Boot configuration information is stored to a volatile memory of a processing system during a low-power state. When resuming from the low-power state, a processor device accesses configuration information for a memory controller from a non-volatile memory and restores the memory controller using the configuration information so as to permit access to the volatile memory. The processor device then configures the initial contexts one or more processor cores using the core state information maintained by the volatile memory during the low-power state and accessed via the configured memory controller, and the one or more processor cores completes the boot process by executing resume boot code maintained by the volatile memory during the low-power state and accessed via the configured memory controller, rather than accessing boot code from a non-volatile memory.
