From 0eb5717a85b6cba3f67c11fa89bdde38dcd081b5 Mon Sep 17 00:00:00 2001 From: Hans-Christian Egtvedt Date: Wed, 6 Aug 2008 14:42:13 +0200 Subject: avr32: add support for EarthLCD Favr-32 board This patch adds support for the Favr-32 board made by EarthLCD. This kit, which is also called ezLCD-101 when running with EarthLCD firmware, has a 10.4" touch screen LCD panel, 16 MB 32-bit SDRAM, 8 MB parallel flash, Ethernet, audio out, USB device, SD-card slot, USART and various other connectors for cennecting stuff to SPI, I2C, GPIO, etc. Signed-off-by: Hans-Christian Egtvedt Signed-off-by: Haavard Skinnemoen --- board/earthlcd/favr-32-ezkit/favr-32-ezkit.c | 96 ++++++++++++++++++++++++++++ 1 file changed, 96 insertions(+) create mode 100644 board/earthlcd/favr-32-ezkit/favr-32-ezkit.c (limited to 'board/earthlcd/favr-32-ezkit/favr-32-ezkit.c') diff --git a/board/earthlcd/favr-32-ezkit/favr-32-ezkit.c b/board/earthlcd/favr-32-ezkit/favr-32-ezkit.c new file mode 100644 index 0000000..22b6981 --- /dev/null +++ b/board/earthlcd/favr-32-ezkit/favr-32-ezkit.c @@ -0,0 +1,96 @@ +/* + * Copyright (C) 2008 Atmel Corporation + * + * See file CREDITS for list of people who contributed to this project. + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the Free + * Software Foundation; either version 2 of the License, or (at your option) + * any later version. + * + * This program is distributed in the hope that it will be useful, but WITHOUT + * ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or + * FITNESS FOR A PARTICULAR PURPOSE.
