5 * (C) Copyright 2003 Josef Baumgartner <josef.baumgartner@telex.de>
9 * Version: U-Boot 1.0.0 - initial release for Sentec COBRA5272 board
11 * Author: Florian Schlote
13 * For a description of configuration options please refer also to the
14 * general u-boot-1.x.x/README file
19 * board/config.h - configuration options, board specific
23 #ifndef _CONFIG_COBRA5272_H
24 #define _CONFIG_COBRA5272_H
27 * Defines processor clock - important for correct timings concerning serial
32 #define CFG_SYS_CLK 66000000
33 #define CFG_SYS_SDRAM_SIZE 16 /* SDRAM size in MB */
36 * Define baudrate for UART1 (console output, tftp, ...)
37 * default value of CONFIG_BAUDRATE for Sentec board: 19200 baud
38 * CFG_SYS_BAUDRATE_TABLE defines values that can be selected in u-boot command
43 #define CFG_SYS_UART_PORT (0)
46 * CONFIG_MONITOR_IS_IN_RAM defines if u-boot is started from a different
47 * bootloader residing in flash ('chainloading'); if you want to use
48 * chainloading or want to compile a u-boot binary that can be loaded into
51 * You will need a first stage bootloader then, e. g. colilo or a working BDM
52 * cable (Background Debug Mode)
54 * Setting #if 0: u-boot will start from flash and relocate itself to RAM
56 * Please do not forget to modify the setting of CONFIG_TEXT_BASE
57 * in board/cobra5272/config.mk accordingly (#if 0: 0xffe00000; #if 1: 0x20000)
63 #define CONFIG_MONITOR_IS_IN_RAM /* monitor is started from a preloader */
67 * Configuration for environment
68 * Environment is embedded in u-boot in the second sector of the flash
72 #define LDS_BOARD_TEXT \
73 . = DEFINED(env_offset) ? env_offset : .; \
74 env/embedded.o(.text);
77 *-----------------------------------------------------------------------------
78 * Define user parameters that have to be customized most likely
79 *-----------------------------------------------------------------------------
82 /*AUTOBOOT settings - booting images automatically by u-boot after power on*/
84 /* The following settings will be contained in the environment block ; if you
85 want to use a neutral environment all those settings can be manually set in
86 u-boot: 'set' command */

92 /* User network settings */
99 *-----------------------------------------------------------------------------
100 * End of user parameters to be customized
101 *-----------------------------------------------------------------------------
105 * Defines memory range for test
110 * Low Level Configuration Settings
111 * (address mappings, register initial values, etc.)
112 * You should know what you are doing if you make changes here.
