The role of EMC is to load EMC | The role of EMC is to load EMC IPL and EAP kernel, to be an interface for icc for the main [[APU]] kernel and [[Syscon]] and to offer a debug interface via UART that does not rely on [[Syscon]] or main APU. EMC runs its own FreeBSD kernel. It is a Marvell Armada, an ARM-based SoC. Sony stuck a [[PCIe]] bridge on it. It exposes ARM peripherals to the x86 side. There is some extra stuff (e.g. HPET, ACPI stuff). | ||
