Describe the Broadcom Hurricane 2 SoC comprised of a Cortex-A9 CPU complex along with standard iProc peripherals: * timers * SPI controller * NAND controller * a single AMAC (Ethernet MAC controller) * dual PCIe controllers The design is largely similar to existing iProc-based SoCs such as Northstar Plus.
