config NVS_ENCRYPTION
bool "Enable NVS encryption"
nvs_flash: Modify the default NVS initialization API with internal nvs encryption handling (only when nvs encryption is enabled) * NVS Encryption will now be turned on by default with flash encryption * Updated the flash encryption example to shocase NVS encryption along with information on how to configure and use NVS encryption * Updated respective test case * Added two partition tables for NVS encryption i) Table 1- Single factory app, no OTA, encrypted NVS ii) Table 2- Factory app, Two OTA, encrypted NVS

This option enables encryption for NVS. When enabled, AES-XTS is used to encrypt
the complete NVS data, except the page headers. It requires XTS encryption keys
to be stored in an encrypted partition. This means enabling flash encryption is
a pre-requisite for this feature.
nvs: add config to ignore "encrypted" flag of nvs partitions This is to allow having pre IDF v4.3 behavior where "encrypted" flag was not being checked for NVS partitions. It is recommended to enable this new config only if you have production devices where NVS partition was being set with "encrypted" flag by mistake. Please see commit aca9ec28b3d091a73605ee89ab63f8f76a996491 which introduced check to not allow NVS partitions with "encrypted" flag set.

config NVS_COMPATIBLE_PRE_V4_3_ENCRYPTION_FLAG
bool "NVS partition encrypted flag compatible with ESP-IDF before v4.3"
depends on SECURE_FLASH_ENC_ENABLED
help
Enabling this will ignore "encrypted" flag for NVS partitions. NVS encryption
scheme is different than hardware flash encryption and hence it is not recommended
to have "encrypted" flag for NVS partitions. This was not being checked in pre v4.3
IDF. Hence, if you have any devices where this flag is kept enabled in partition
table then enabling this config will allow to have same behavior as pre v4.3 IDF.
add: Kconfig assert or errorcode option add: private include header add: macro encapsulation for assertion or error check add: ESP_FAIL return code documentation in public headers change: replaced all assertions by NVS_ASSERT_OR_RETURN macro change: few internal function return values from void to esp_err_t change: ESP_ERR_NVS_VALUE_TOO_LONG macro comment

This option switches error checking type between assertions (y) or return codes (n).
