esp8288 nodemcu wps support

For a project I need wps support in the nodemcu firmware. To enable that I have added wifi.wps.* commands in app/modules/wifi.c and I have added -lwps to the Makefile in app. All builds well, but after flashing the firmware I get problems in that the firmware reboots in a loop.

Commenting out the calls to libwps.a and only having the lua commands in place makes the problem disappear. Is there a know issue, why there is no wps support in nodemcu?

I have a clone of the nodemcu git repository and a docker build environment for building the firmware.

Found out that if I use the ESPTOOL_FS environment variable of esptool.py to set the correct flash memory size, the firmware size can be greater than 512K and there are no problems starting the module.

Found the problem myself. There seems to be a limit of the firmware size of 512 KB. I removed some modules when building to stay under that limit and then all worked as expected :)
