Fri Nov 3 10:10:55 UTC 2017
From: Peter Senna Tschudin <peter.senna at collabora.com>
Create board support for GE PPD, based on mx53loco.
Use mx53ppd_defconfig make target to configure for this board.

Changes in v4:
- Remove mach-type.h entry.
- Move to ge board directory (to be able to use ge common code).
- Remove now common VPD code.
- Move do_lcd_enable() to mx53ppd_video.c.
