Sun Dec 13 12:09:58 CET 2015
Signed-off-by: Michael Heimpold <mhei at heimpold.de>
---
Please note, that this board setup files need the function
mxs_power_switch_dcdc_clocksource() as introduced in my patch
"ARM: mxs: allow boards to select DC-DC switching clock source"
Changes in v2:
- added autoboot stuff
- reworked tftp update workflow
- added dc-dc clock source configuration
Changes in v1:
- initial public submission
