The Odroid Go Advance uses a Rockchip Serial Flash Controller with an XT25F128B SPI NOR flash chip. This adds support for both. Note that while both the controller and chip support quad mode, only two lines are connected to the chip. Changing the pinctrl to bus2 and setting tx and rx lines to 2 for this reason.
