From ea8bc0b643ba31d5b74ea3c018956b832b98dc5a Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Thu, 24 Oct 2013 18:20:35 +0200 Subject: colibri_vf61: initial integration Add initial Colibri VF61 support based off Timesys' implementation for Freescale's Vybrid Tower System TWR-VF65GS10: - New machine ID. - Default UART_A on SCI0. - ESDHC2 only. - 8-bit NAND. - No quad SPI. - FEC1 only. - Enabled command line editing. - PLL5 based RMII clocking (e.g. no external crystal). - UART_A, UART_B and UART_C I/O muxing. - Increase the available space for the U-Boot binary to half a megabyte by booting from gfxRAM rather than sysRAM0. - Integrate factory configuration block handling for hardware version, MAC address and serial number to be passed to Linux. - The U-Boot environment is stored in NAND flash. - Fix long standing boot hang issue introduced by Freescale's Vybrid 1.1 silicon. - Proper 256 MB Nanya DDR3 RAM timings. Tested on early Colibri VF61 prototypes V1.0b and V1.0c using SD card (mandatory for initial loading) as well as NAND boot. --- include/configs/colibri_vf61_sdboot.h | 59 +++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 include/configs/colibri_vf61_sdboot.h (limited to 'include/configs/colibri_vf61_sdboot.h') diff --git a/include/configs/colibri_vf61_sdboot.h b/include/configs/colibri_vf61_sdboot.h new file mode 100644 index 0000000000..dbb05929aa --- /dev/null +++ b/include/configs/colibri_vf61_sdboot.h @@ -0,0 +1,59 @@ +/* + * Copyright 2013 Toradex, Inc. + * + * Configuration settings for the Colibri VF50 module booting from SD card. + * + * 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.
