CONFIG_PMB: Support 32-bit physical addressing through PMB

General informations

The Linux kernel configuration item CONFIG_PMB has multiple definitions:

Support 32-bit physical addressing through PMB found in arch/sh/mm/Kconfig

The configuration item CONFIG_PMB:

• prompt: Support 32-bit physical addressing through PMB
• type: bool
• depends on: CONFIG_MMU && CONFIG_CPU_SH4A && ! CONFIG_CPU_SH4AL_DSP
• defined in arch/sh/mm/Kconfig
• found in Linux kernels: 2.6.25–2.6.29, 2.6.34–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12

Help text

If you say Y here, physical addressing will be extended to 32-bits through the SH-4A PMB. If this is not set, legacy 29-bit physical addressing will be used.
