Flashrom compatible firmware to read/write/erase flash chips

This firmware can be installed on serveral Arduinos with AVR microcontrollers. You then need to connect the Arduino between a computer running flashrom and to a flash chip. With flashrom (for instance with flashrom -p serprog:dev=/dev/ttyUSB0:2000000) you can then read/write/erase various SPI flash chip supported by flashrom.

But I've still set this firmware to GPLv3 or later as it uses libfrser that is GPLv3 or later as some of its files are under that license. libfrser is also included in the source code tough git submodules, and the code is compiled directly in frser-duino.

Two headers contain configuration (spihw.h, frser-cfg.h) and have no license header but the license is covered by the header in the other files ("This program is free software [...]").
