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
Commit 5e8795eebe has changed the partition table offset, which
has resulted in the ciphertext not matching the one expected in the
example test.
Fix by calculating the ciphertext using espsecure.py.
When the flash encryption is enabled then we do not need to change the partition table.
The partition_example.csv should not have fixed offsets for partitions because we want to move the whole table.
The fixed offsets in the table were cleared.
This MR improves existing flash encryption document to provide simplified steps
Adds two new modes for user: Development & Release
Adds a simple example
Supports encrypted write through make command
