CONFIG_MEMORY_START: Physical memory start address

General informations

The Linux kernel configuration item CONFIG_MEMORY_START has multiple definitions:

Physical memory start address found in arch/sh/mm/Kconfig

The configuration item CONFIG_MEMORY_START:

• prompt: Physical memory start address
• type: hex
• depends on: (none)
• defined in arch/sh/mm/Kconfig
• found in Linux kernels: 2.6.19–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

Computers built with Hitachi SuperH processors always map the ROM starting at address zero. But the processor does not specify the range that RAM takes.

The physical memory (RAM) start address will be automatically set to 08000000. Other platforms, such as the Solution Engine boards typically map RAM at 0C000000.

Tweak this only when porting to a new machine which does not already have a defconfig. Changing it from the known correct value on any of the known systems will only lead to disaster.
