issues for 'app'.

help
Use the ELM FAT File system implementation.
config FILE_SYSTEM_NFFS
bool "NFFS file system support"
depends on FLASH_PAGE_LAYOUT
help
Enables NFFS file system support.
Note: NFFS requires 1-byte unaligned access to flash thus it
will not work on devices that support only aligned flash access.

help
Enables LittleFS file system support.

This defines maximum number of areas located on flash. Each area can
be erased without affecting other areas thus the size of area can
affect performance of GC where single area has to be rewritten.
At least one scratch and one non-scratch area is required.

This determines the maximum size of data block written to flash.
Writes larger than this size are split into multiple write operations.
