====== Ota on 1MB devices ======

ESP always boot from app image.
During OTA rest of flash is used as temporary buffer to perform OTA.

So on 1MB chip the real usable space can be:
  - 1024kB flash
  - minus 128kB SPIFFS
  - 896kB avail flash
  - minus small OTA 
  - 896kB-281kB = 615kB


===== workarounds =====
