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
17 The processor cores in the sub-system are usually behind an IOMMU, and may
18 contain additional sub-modules like Internal RAM and/or ROMs, L1 and/or L2
21 The OMAP SoCs usually have a DSP processor sub-system and/or an IPU processor
