From b5b06fb7b04a93ea48638d4d2ba1932051a28f64 Mon Sep 17 00:00:00 2001 From: York Sun Date: Sun, 23 Dec 2012 19:25:27 +0000 Subject: powerpc/b4860qds: Added Support for B4860QDS B4860QDS is a high-performance computing evaluation, development and test platform supporting the B4860 QorIQ Power Architecture processor. B4860QDS Overview ------------------ - DDRC1: Ten separate DDR3 parts of 16-bit to support 72-bit (ECC) at 1866MT/s, ECC, 4 GB of memory in two ranks of 2 GB. - DDRC2: Five separate DDR3 parts of 16-bit to support 72-bit (ECC) at 1866MT/s, ECC, 2 GB of memory. Single rank. - SerDes 1 multiplexing: Two Vitesse (transmit and receive path) cross-point 16x16 switch VSC3316 - SerDes 2 multiplexing: Two Vitesse (transmit and receive path) cross-point 8x8 switch VSC3308 - USB 2.0 ULPI PHY USB3315 by SMSC supports USB port in host mode. - B4860 UART port is available over USB-to-UART translator USB2SER or over RS232 flat cable. - A Vitesse dual SGMII phy VSC8662 links the B4860 SGMII lines to 2xRJ-45 copper connectors for Stand-alone mode and to the 1000Base-X over AMC MicroTCA connector ports 0 and 2 for AMC mode. - The B4860 configuration may be loaded from nine bits coded reset configuration reset source. The RCW source is set by appropriate DIP-switches: - 16-bit NOR Flash / PROMJet - QIXIS 8-bit NOR Flash Emulator - 8-bit NAND Flash - 24-bit SPI Flash - Long address I2C EEPROM - Available debug interfaces are: - On-board eCWTAP controller with ETH and USB I/F - JTAG/COP 16-pin header for any external TAP controller - External JTAG source over AMC to support B2B configuration - 70-pin Aurora debug connector - QIXIS (FPGA) logic: - 2 KB internal memory space including - IDT840NT4 clock synthesizer provides B4860 essential clocks : SYSCLK, DDRCLK1, 2 and RTCCLK. - Two 8T49N222A SerDes ref clock devices support two SerDes port clocks - total four refclk, including CPRI clock scheme Signed-off-by: York Sun Signed-off-by: Prabhakar Kushwaha Signed-off-by: Shaveta Leekha Signed-off-by: Priyanka Jain Signed-off-by: Poonam Aggrwal Signed-off-by: Roy Zang Signed-off-by: Sandeep Singh Signed-off-by: Andy Fleming --- board/freescale/b4860qds/b4860qds.c | 458 ++++++++++++++++++++++++++++++++++++ 1 file changed, 458 insertions(+) create mode 100644 board/freescale/b4860qds/b4860qds.c (limited to 'board/freescale/b4860qds/b4860qds.c') diff --git a/board/freescale/b4860qds/b4860qds.c b/board/freescale/b4860qds/b4860qds.c new file mode 100644 index 00000000000..88bdc1f65f1 --- /dev/null +++ b/board/freescale/b4860qds/b4860qds.c @@ -0,0 +1,458 @@ +/* + * Copyright 2011-2012 Freescale Semiconductor, Inc. + * + * 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.
