- Set correct include paths for nonos-sdk - Set correct libraries list - Suppress literal-suffix warnings from SDK building - Avoid building SDK drivers on each run for nonos-sdk - Remove dependency to xtensa 1.40802.0 in platform.py
platform.json - Update nonos-sdk and rtos-sdk version numbers esp8266-nonos-sdk.py - Add SPI_FLASH_SIZE_MAP to compile flags - Use the new "esp_init_data_default_v08.bin" file for NONOS 3.0.4
Requires package tool-genbin Implemented as a target in pio: pio -t upload -t ota main.py - add ota target - allow different bootloader nonos-sdk and rtos-sdk - use genbin.py to create binaries instead Espressif's gen_appbin.py - set correct arguments list for flashing platform.json - add dependancy to genbin

I'm finalizing a new version which supports ESP8266-RTOS-SDV v3.4. I will rather make a push request on the new version |

This PR implements support for the latest Espressif nonos-sdk (second commit) and support for legacy OTA usable with nonos-sdk and rtos-sdk (v1.5) (third commit).
I know that Espressif is phasing out nonos-sdk, but I prefer avoid arduino framework and still use these two ones until rtos3-sdk is available.
Support for the Espressif nonos-sdk (3.0.5) requires :
To achieve that, the platform builder :
A fork of latest Espressif nonos-sdk with the addition of package.json is available at https://github.com/freedib/framework-esp8266-nonos-sdk.
To support for legacy OTA, the platform must create binaries for user1 and user2 which can be stored on an http server. If direct upload is required, user1 binary must be uploaded.
A new "ota" target is created in main.py. If used, then OTA files be generated. If not, non OTA files will be generated.
A python tool (genbin.py) similar to Espressif's gen_appbin.py allow to extract elf sections and create flash.bin+irom0.text.bin (non OTA) or user1.bin+user2.bin (OTA).
To achieve that, the platform builder :
The same code is used for nonos-sdk and rtos-sdk.
genbin.py is already packaged for platformio and available at https://github.com/freedib/tool-genbin.
