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 Changes v2 > v3 - improve spelling in README - added own copy of mx6q_4x_mt41j128.cfg Signed-off-by: Christian Gmeiner --- board/bachmann/ot1200/README | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 board/bachmann/ot1200/README (limited to 'board/bachmann/ot1200/README') diff --git a/board/bachmann/ot1200/README b/board/bachmann/ot1200/README new file mode 100644 index 0000000..c03d44e --- /dev/null +++ b/board/bachmann/ot1200/README @@ -0,0 +1,20 @@ +U-Boot for the Bachmann electronic GmbH OT1200 devices + +There are two different versions of the base board, which differ +in the way ethernet is done.
