From 522e4fbb7676de12767b61ce89cef6656476809e Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Wed, 16 Dec 2015 17:01:44 +0100 Subject: ARM: Add Support for the VInCo platform MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Versatile Industrial Communication platform is a community oriented board from Landis + Gyr. It comes with: - an RS-485 port - 2 Ethernet ports - a wireless M-BUS - a 4G modem - a 4MB SPI flash - a 4GB eMMC Signed-off-by: Gregory CLEMENT Acked-by: Nicolas Ferre [rebase on current TOT] Signed-off-by: Andreas Bießmann --- board/l+g/vinco/Kconfig | 12 +++ board/l+g/vinco/Makefile | 1 + board/l+g/vinco/vinco.c | 212 +++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 225 insertions(+) create mode 100644 board/l+g/vinco/Kconfig create mode 100644 board/l+g/vinco/Makefile create mode 100644 board/l+g/vinco/vinco.c (limited to 'board/l+g') diff --git a/board/l+g/vinco/Kconfig b/board/l+g/vinco/Kconfig new file mode 100644 index 0000000000..229b5ea129 --- /dev/null +++ b/board/l+g/vinco/Kconfig @@ -0,0 +1,12 @@ +if TARGET_VINCO + +config SYS_BOARD + default "vinco" + +config SYS_VENDOR + default "l+g" + +config SYS_CONFIG_NAME + default "vinco" + +endif diff --git a/board/l+g/vinco/Makefile b/board/l+g/vinco/Makefile new file mode 100644 index 0000000000..a2b8a2bc4a --- /dev/null +++ b/board/l+g/vinco/Makefile @@ -0,0 +1 @@ +obj-y += vinco.o diff --git a/board/l+g/vinco/vinco.c b/board/l+g/vinco/vinco.c new file mode 100644 index 0000000000..3d7af092e8 --- /dev/null +++ b/board/l+g/vinco/vinco.c @@ -0,0 +1,212 @@ +/* + * Board file for the VInCo platform + * Based on the the SAMA5-EK board file + * Configuration settings for the VInCo platform. + * Copyright (C) 2014 Atmel + * Bo Shen + * Copyright (C) 2015 Free Electrons + * Gregory CLEMENT + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +DECLARE_GLOBAL_DATA_PTR;
