| 5 | This is the framework for the SPI NOR which can be used by the SPI | |
| 6 | device drivers and the SPI-NOR device driver. | |

| 13 | help | |
| 14 | Many flash memories support erasing small (4096 B) sectors. Depending | |
| 15 | on the usage this feature may provide performance gain in comparison | |
| 16 | to erasing whole blocks (32/64 KiB). | |
| 17 | Changing a small part of the flash's contents is usually faster with | |
| 18 | small sectors. On the other hand erasing should be faster when using | |
| 19 | 64 KiB block instead of 16 × 4 KiB sectors. | |
| 20 | ||
| 21 | Please note that some tools/drivers/filesystems may not work with | |
| 22 | 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum). | |

| 28 | This enables support for the Quad SPI controller in master mode. | |
| 29 | We only connect the NOR to this controller now. | |

| 36 | Enable support for the NXP LPC SPI Flash Interface controller. | |
| 37 | ||
| 38 | SPIFI is a specialized controller for connecting serial SPI | |
| 39 | Flash. Enable this option if you have a device with a SPIFI | |
| 40 | controller and want to access the Flash as a mtd device. | |
