| help |
| When CONFIG_FLASH_PAGE_LAYOUT is used this driver will support |
| that API. By default the page size corresponds to the block |
| size (65536). Other option include the sector size (4096). |

| config NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE |
| int "Size of a stack-based buffer to handle writes not supported by QSPI" |
| default 4 |
| help |
| The QSPI peripheral uses DMA and can only write data that is read |
| from a word-aligned location in RAM. A non-zero value here enables |
| a stack buffer to be used for any source data that does not meet |
| these restrictions. Such data will be copied into this buffer to |
| allow the write to proceed. Multiple transfers will be initiated |
| if the data is larger than the configured size. |
| Must be a multiple of 4. When set to 0, the feature is disabled. |

| config NORDIC_QSPI_NOR_XIP |
| bool "XIP (eXecute in place)" |
| depends on SOC_NRF5340_CPUAPP |
| help |
| Enable setting up the QSPI NOR driver to allow for execution of code |
| stored in QSPI XIP region. Note that for this functionality to work, |
| the QSPI NOR init priority must be set so that no XIP code in the |
| QSPI NOR flash chip is executed until the driver has been setup. |
| This will also disable power management for the QSPI NOR flash chip. |
| |
| config NORDIC_QSPI_NOR_TIMEOUT_MS |
| int "Timeout for QSPI operations (ms)" |
| default 500 |
| help |
| The QSPI peripheral operation timeout in milliseconds. |
| Primarily intended for long running operations such as |
| a flash sector erase. The 500 ms default allows for |
| most typical NOR flash chips to erase a sector. |
