| default y |
| 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). |
