CONFIG_MTD_PHYSMAP: Flash device in physical memory map

General informations

The Linux kernel configuration item CONFIG_MTD_PHYSMAP has multiple definitions:

Flash device in physical memory map found in drivers/mtd/maps/Kconfig

The configuration item CONFIG_MTD_PHYSMAP:

• prompt: Flash device in physical memory map
• type: tristate
• depends on: CONFIG_MTD_CFI || CONFIG_MTD_JEDECPROBE || CONFIG_MTD_ROM || CONFIG_MTD_RAM || CONFIG_MTD_LPDDR
• defined in drivers/mtd/maps/Kconfig
• found in Linux kernels: 2.6.29–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: physmap

Help text

This provides a 'mapping' driver which allows the NOR Flash and ROM driver code to communicate with chips which are mapped physically into the CPU's memory. You will need to configure the physical address and size of the flash chips on your particular board as well as the bus width, either statically with config options or at run-time.

To compile this driver as a module, choose M here: the module will be called physmap.
