Enable support of Zephyr Memory Storage.

bool "ZMS lookup cache"
help
Enable ZMS cache to reduce the ZMS data lookup time.
Each cache entry holds an address of the most recent allocation
table entry (ATE) for all ZMS IDs that fall into that cache position.

help
Number of entries in ZMS lookup cache.
It is recommended that it should be a power of 2.
Every additional entry in cache will add 8 bytes in RAM
config ZMS_DATA_CRC
bool "ZMS DATA CRC"
help
Enables DATA CRC
config ZMS_CUSTOMIZE_BLOCK_SIZE
bool "Customize the size of the buffer used internally for reads and writes"
help
ZMS uses an internal buffer to read/write and compare stored data.
Increasing the size of this buffer should be done carefully in order to not
overflow the stack.
Increasing this buffer means as well that ZMS could work with storage devices
that have larger write-block-size which decreases ZMS performance
config ZMS_CUSTOM_BLOCK_SIZE
int "ZMS internal buffer size"
default 32
depends on ZMS_CUSTOMIZE_BLOCK_SIZE
help
Changes the internal buffer size of ZMS
