| 14 | This enables access to SPI NOR flash, using MT81xx SPI NOR flash | |
| 15 | controller. This controller does not support generic SPI BUS, it only | |
| 16 | supports SPI NOR Flash. | |

| 21 | help | |
| 22 | Many flash memories support erasing small (4096 B) sectors. Depending | |
| 23 | on the usage this feature may provide performance gain in comparison | |
| 24 | to erasing whole blocks (32/64 KiB). | |
| 25 | Changing a small part of the flash's contents is usually faster with | |
| 26 | small sectors. On the other hand erasing should be faster when using | |
| 27 | 64 KiB block instead of 16 × 4 KiB sectors. | |
| 28 | ||
| 29 | Please note that some tools/drivers/filesystems may not work with | |
| 30 | 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum). | |
