bool "Read flash parameters at runtime"
help
Read flash device characteristics from the device at runtime.
This option should provide functionality for all supported
JESD216-compatible devices, with the following notes:
- Quad Enable Requirements bitfield (DW15) must be present in the SFDP
tables to configure Quad mode. Otherwise it defaults to Dual or
Single mode as supported by the device.
- Soft Reset bitfield (DW16) must be present in the SFDP tables to
automatically reset the device at initialization time.
- 0-X-X mode discovery not yet implemented by the HAL.
If not selected, the driver uses a fixed configuration assuming 256 By
page size and 4 KiBy, 32 KiBy and 64 KiBy erase instructions. The
device size and jedec-id properties must be set in devicetree node.

help
When CONFIG_FLASH_PAGE_LAYOUT is used this driver will support that API.
By default the page size corresponds to the sector size (4096) for a NOR
flash memory. Other options may include the 32K-byte erase size (32768),
the block size (65536), or any non-zero multiple of the sector size.
