13 The OMAP family of SoCs usually have one or more slave processor sub-systems
14 that are used to offload some of the processor-intensive tasks, or to manage
15 other hardware accelerators, for achieving various system level goals.
17 The processor cores in the sub-system are usually behind an IOMMU, and may
