This patch introduces a framebuffer to Minix. It's written for the ARM port of Minix, but has an architectural split that separates the hardware dependent part from the non-hardware dependent part. Futhermore, this driver was developed using a screen that has a native resolution of 1024x600 pixels and having lack of support for obtaining EDID from the screen. Consequently, it uses a hardcoded resolution of 1024x600. The driver uses an interface based on the Linux ioctl API, but supports only a very limited subset.
