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 options include the 32K-byte erase size (32768), the sector
|
|
size (4096), or any non-zero multiple of the sector size.

If size is larger than this number, it is uneconomical to handle cache in range.

However, this is a number by experience and could be platform specific.
