[U-Boot] [PATCH v3] arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC
From: Patrick Bruenn p.bruenn@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@beckhoff.com
---
Changes in v3: - replace CONFIG_TARGET_MX53CX9020 with CONFIG_MX53 in dts/Makefile - remove redundant CONFIG_DISPLAY_BOARDINFO from mx53cx9020.h
Changes in v2: - remove #include <asm/errno.h> from mx53cx9020.c - remove obsolete CONFIG_CMD_CCAT from mx53cx9020.h

From: Patrick Bruenn p.bruenn@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@beckhoff.com
Changes in v3:
- replace CONFIG_TARGET_MX53CX9020 with CONFIG_MX53 in dts/Makefile
- remove redundant CONFIG_DISPLAY_BOARDINFO from mx53cx9020.h
Changes in v2:
- remove #include <asm/errno.h> from mx53cx9020.c
- remove obsolete CONFIG_CMD_CCAT from mx53cx9020.h

Maybe, but I didn't find a working solution. From your experience should the cyclone2 driver work for cyclon3 as well?
