[U-Boot] [PATCH v2] arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC
linux-kernel-dev at beckhoff.com
linux-kernel-dev at beckhoff.com
Fri Oct 7 18:14:49 CEST 2016
From: Patrick Bruenn <p.bruenn at beckhoff.com>
Add CX9020 board based on mx53loco.
Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse
serial_mxc with DTE and prepare for device tree migration of other
functions and imx53 devices.
The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc
Signed-off-by: Patrick Bruenn <p.bruenn at beckhoff.com>
---
Changes in v2:
- remove #include <asm/errno.h> from mx53cx9020.c
- remove obsolete CONFIG_CMD_CCAT from mx53cx9020.h
