1) added the ILI9325 platform definition in the arch/arm/mach-bcm2708/bcm2708.c File
static struct platform_device bcm2708_ili9325 = {.name = "ili9325",.id = 0,};/*************************/bcm_register_device(bcm2708_ili9325);
2) modified the drivers/video/Kconfig file and added:

prove that Snappy is a system for cloud computing, especially for Iot.
Snappy can also run on other clouds such as Amazon EC2, Microsoft Azure, and Google's Compute Engine. It can also be virtualized on KVM, Virtuabox, and vagrant. Canonical Ubuntu has embraced heavyweight players such as Microsoft, Google, Docker, and OpenStack, and has reached partnerships with small projects. In addition to some startups, such as Ninja Sphere and Erle Robotics, th
