Wed Nov 1 14:23:09 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 for v2:
- Replacing boot count related defines with default config.
Changes for v3:
- Update config due to BOOTCOUNT Kconfig addition.
