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. | |

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). | |

47 | Cadence QSPI is a specialized controller for connecting an SPI | |
48 | Flash over 1/2/4-bit wide bus. Enable this option if you have a | |
49 | device with a Cadence QSPI controller and want to access the | |
50 | Flash as an MTD device. | |
