This driver blocks on a semaphore to receive notification when an operation is complete, so requires CONFIG_MULTITHREADING=y. Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>

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).

help
|
|
The QSPI peripheral uses DMA and cannot write data that is
|
|
read from the internal flash. A non-zero value here enables
|
|
a stack buffer into which data is copied to allow the write
|
|
to proceed. Multiple transfers will be initiated if the
|
|
data is larger than the configured limit. Must be a
|
|
multiple of 4. The feature is disabled when set to 0.
