I thought I read the solution somewhere in the past but can't find it anymore.
I would like to know if it would be possible to flash the ESP8266 through its SPI to load Arduino IDE, LUA, etc.. . In a few words, replace the UART Tx/Rx interface with the SPI.
One of the use would be to increase the loading speed and use this kind of USB to SPI converter http://www.ftdichip.com/Products/ICs/FT220X.html
I would be very happy if you could feed my curiosity,
Cheers,
