Version 1: - Initial commit
The purpose of this set of patches is to add a new driver for stm32f429. This driver was developed and tested on evaluation board stm32429i.
Stm32f4 is a MCU platform which don't have MMU so the last patches developed by Benjamin Gaignard regarding "DRM: allow to use mmuless devices" are necessary.
The board stm429i embeds a Ampire AM-480272H3TMQW-T01H screen. A new simple panel am-480272h3tmqw-t01h have been added to support it.
