| 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 |
| module will be called physmap. |

| This is the total length of the mapping of the flash chips on |
| your particular board. If there is space, or aliases, in the |
| physical memory map between the chips, this could be larger |
| than the total amount of flash present. Refer to the memory |

| help |
| This is the total width of the data bus of the flash devices |
| in octets. For example, if you have a data bus width of 32 |
| bits, you would set the bus width octet value to 4. This is |
| used internally by the CFI drivers. |
