| help |
| 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 |
