Wed Mar 13 13:31:30 CET 2013
From: Fabio Estevam <fabio.estevam at freescale.com>
Add initial support for Wandboard.
Wandboard is a development board that has two variants: one version based
on mx6 dual lite and another one based on mx6 solo.
For details on the features of Wandboard, please refer to:
http://www.wandboard.org/
Signed-off-by: Fabio Estevam <fabio.estevam at freescale.com>
---
Changes since v2:
- Also added support to the mx6solo variant.
- Rebased against u-boot-imx
Changes since v1:
- Use get_ram_size
- Remove ARP_TIMEOUT
- Remove unneeded "1u"
