//------------------------------------------------------------------------------

// NOTE
// DSP Subsystem has the following modules.
// 1. DSP Core       - Accessible from only DSP IO space
// 2. dINTC          - DSP memory space
// 3. DSP SS Global  - DSP memory space
// 4. dDMA           - DSP memory space
// 5. DSP MMU        - OMAP 24xx memory space
// 6. IPI            - OMAP 24xx memory space

// Since the items 1-4 are accessible only from DSP IO and memory space
// the structures for them will not be defined from the ARM side.
// The item DSP MMU is already defined under MMU section.
// So the structures will be created for the IPI registers alone.

//
// IPI Register - SEE omap2420_base_regs.h base address OMAP2420_DSP_IPI_REGS_PA
