DSP support found in arch/sh/Kconfig.cpu

The configuration item CONFIG_SH_DSP:

• prompt: DSP support
• type: bool
• depends on: CONFIG_CPU_HAS_DSP
• defined in arch/sh/Kconfig.cpu
• found in Linux kernels: 2.6.25–2.6.39, 3.0–3.9, 3.10-rc+HEAD

Help text

Selecting this option will enable support for SH processors that have DSP units (ie, SH2-DSP, SH3-DSP, and SH4AL-DSP).

This option must be set in order to enable the DSP.

DSP support found in arch/sh/Kconfig

The configuration item CONFIG_SH_DSP:

• prompt: DSP support
• type: bool
• depends on: ! CONFIG_CPU_SH4
• defined in arch/sh/Kconfig
• found in Linux kernels: 2.6.2–2.6.24

Help text

Selecting this option will enable support for SH processors that have DSP units (ie, SH2-DSP and SH3-DSP). It is safe to say Y here by default, as the existance of the DSP will be probed at runtime.

This option must be set in order to enable the DSP.
