As extension on this PR: #4988

That PR added a config for:

Flash Split for 2M chips

  • sketch 1019KB
  • spiffs 1004KB
  • eeprom 20KB

But that layout does only allow for OTA update of sketches up-to 510k (or a bit more when using two-step update)
So I guess for the Shelly1 and other 2M modules it would be more useful to have 256k or 512k SPIFF and 20k EEPROM. The rest should then be available for the sketch, to allow for easier OTA updates.

For example:

  • sketch 1516 kB
  • spiffs 512 kB
  • eeprom 20 kB

flash_size(0x200000, '2M', '2m512', '512K SPIFFS', 1044464, 0x17B000, 0x80000, 8192)

[Shelly1] Add first test build for Shelly1 nodes
272ed8c 
[Shelly1 Open Source (ESP8266-2MB)](https://shelly.cloud/shelly1-open-source/)
This is a preliminary test version as I have not yet received my ordered modules.
Also there is a [feature request](esp8266/Arduino#5096 (comment)) out for adding proper flash layout for these 2M flash modules which allow proper OTA.
