15 | This provides a 'mapping' driver which allows the NOR Flash and |
16 | ROM driver code to communicate with chips which are mapped | |
17 | physically into the CPU's memory. You will need to configure | |
18 | the physical address and size of the flash chips on your | |
19 | particular board as well as the bus width, either statically | |
1da177e4 LT |
20 | with config options or at run-time. |

401 | This driver allows for discovery of PISMO modules - see | |
402 | <http://www.pismoworld.org/>. These are small modules containing | |
403 | up to five memory devices (eg, SRAM, flash, DOC) described by an | |
404 | I2C EEPROM. | |
405 | ||
406 | This driver does not create any MTD maps itself; instead it | |
407 | creates MTD physmap and MTD SRAM platform devices. If you | |
408 | enable this option, you should consider enabling MTD_PHYSMAP | |
409 | and/or MTD_PLATRAM according to the devices on your module. | |
410 | ||
411 | When built as a module, it will be called pismo.ko | |

417 | Map driver which allows flashes to be partially physically addressed | |

420 | If compiled as a module, it will be called latch-addr-flash. | |
