From: Linus Walleij <linus.wall...@linaro.org> This adds the SiI9022 (and implicitly EDID I2C) device to the ARM Versatile Express machine, and selects the two I2C devices necessary in the arm-softmmu.mak configuration so everything will build smoothly.
I am implementing proper handling of the graphics in the Linux kernel and adding proper emulation of SiI9022 and EDID makes the driver probe as nicely as before, retrieving the resolutions supported by the "QEMU monitor" and overall just working nice.
