Reduce number of components on my build

[thierryc49]

Hello,

I use an ESP8266 module with 1Mbyte flash, I would like for my project to ass FOTA feature, in this case I have approx 450ko for each binary app. When I use the sample code "native_ota\1MB_flash\new_to_new_no_old" the binary have 440ko flash size then work on my my module. But I just Add smatConfig and MQTT (very simple code for now) but the size go to 456ko. Then this binary is too large to enter in my module.
Because some of components is not needed for my application, I would like to know how I can reduce the number of component linked in my projet.

Thanks a lot for your help

Thierry
