- BDL provider can be enabled vor NVS in the menuconfig option NVS_BDL_STACK
- Hierarchy of Partition class tree was adjusted and all operations were documented
- Class Partition is now derived from intrusive_list_node and ExceptionlessAllocable
- Class NVSPartition implements only the dual support for esp_partition and BDL
- Class NVSEncryptedPartition implements only encryption related extensions
- This features allows the NVS encryption keys to be derived and protected using
the HMAC peripheral. Since the encryption keys are derived at runtime, they
are not stored anywhere in the flash and hence this feature does not require
a separate `nvs_keys` partition.
* partition api changed from spi_flash* API to
esp_partition* API and is abstracted as a C++
interface.
* The old nvs encryption is still possible
* changed default unit test app partition table
* Partitions coming from esp_partition API are
checked for generic flash encryption. If yes,
an error is returned since generic flash
encryption isn't compatible with nvs
encryption
* esp32, esp32s2 tests don't require nvs_flash
but mbedtls now
