[PATCH v2 2/2] ARM: i.MX6: add initial support for SolidRun Cubox-i Carrier-1

Lucas Stach l.stach at pengutronix.de
Mon Dec 2 13:21:20 EST 2013 

Tested to work:
- MMC
- USB
- Ethernet

Signed-off-by: Lucas Stach <l.stach at pengutronix.de>
---
v2:
- move barebox partition setup into DT
- rename flash header to avoid naming collision
- enable ethernet (needs commit "ARM: i.mx53: Parse Reset GPIO pin
  in FEC driver from Devicetree", which is already in -next)
