[U-Boot] [PATCH] imx6: add Bachmann OT1200 board v2

Christian Gmeiner christian.gmeiner at gmail.com
Mon Sep 22 13:57:55 CEST 2014


This patch adds support for the OT1200 series of devices.

Following components are used in u-boot:
+ ethernet
+ i2c
+ emmc
+ gpio

For more details see README.

Changes v1 > v2
  - make use of enable_cspi_clock(..)
  - fix usage of OUTPUT_40OHM define
  - added README

+U-Boot for the Bachmann electronic GmbH OT1200 devices
+
+There are two different versions of the base print, which differ
+in the way ethernet is done. The variant detection is done during
+runtime based on the address of the found phy.
+
+- "mr" variant
+FEC is connected directly to an ethernet switch (KSZ8895). The ethernet
+port is always up and auto-negotiation is not possible.
+
+- normal variant
+FEC is connected to a normal phy and auto-negotiation is possible.
+
+
+The variant name is part of the dtb file name loaded by u-boot. This
+make is possible to boot the linux kernel and make use variant specific
+devicetree (fixed-phy link).
+
+In order to support different display resoltuions/sizes the OT1200 devices
+are making use of EDID data stored in an i2c EEPROM.
