CONFIG_MTD_PHYSMAP_OF: Flash device in physical memory map based on OF descirption

General informations

The Linux kernel configuration item CONFIG_MTD_PHYSMAP_OF has multiple definitions:

Flash device in physical memory map based on OF descirption found in drivers/mtd/maps/Kconfig

The configuration item CONFIG_MTD_PHYSMAP_OF:

• prompt: Flash device in physical memory map based on OF descirption
• type: tristate
• depends on: CONFIG_PPC_OF && ( CONFIG_MTD_CFI || CONFIG_MTD_JEDECPROBE || CONFIG_MTD_ROM )
• defined in drivers/mtd/maps/Kconfig
• found in Linux kernels: 2.6.20–2.6.21
• modules built: physmap_of

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. The mapping description here is taken from OF device tree.
