There are ready-to-use FT2232H-based boards: * FT2232H-56Q Mini-Module (http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm#FT2232H-56_Mini) * FT2232 breakout board (http://dangerousprototypes.com/docs/FT2232_breakout_board) The main goal of adding gpio functionality to sandbox barebox is using it for connecting real i2c and spi devices to sandbox barebox. Sample dts-file for at24 i2c eeprom and at25 spi flash is included. Changes since v1 patch series (http://lists.infradead.org/pipermail/barebox/2017-October/031306.html): * rebase on top barebox v2017.12.0; * ds1307 i2c rtc driver works fine (i2c-gpio,scl-output-only is used); * parseopt_* functions are used for cmdline parsing. Changes since RFC v1 patch series (http://lists.infradead.org/pipermail/barebox/2017-February/029106.html): * rebase on top barebox v2017.10.0; * libftdi cmdline options are added; * device tree support is added.
