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

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