[U-Boot] [PATCH 4/5] imx6: add ot1200 mr board
Christian Gmeiner
christian.gmeiner at gmail.com
Wed Jan 8 08:24:24 CET 2014
This patch add support for one device of the Bachmann OT1200
series - the mr variant.
My first attemp was to use one u-boot binary for all OT1200
devices, but as I need to load a device-specific devicetree
I decided to go this way.
Following components are used:
+ ethernet
+ usb
+ i2c
+ display connected via ldb (init and usage in linux only)
+ emmc
