- Add the function esptool_py_flash_to_partition to flash a binary image to a named partition. If encryption is enabled, this function will also determine if the partition needs to be encrypted or not according the its type, subtype and flag in the CSV file (if any). - Use idf.py encrypted-flash will now flash both encrypted and non-encrypted file if any (spiffs for example) using esptool.py's --encrypt-files option.
