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 CONFIG_SYS_CLK 66000000
33 #define CONFIG_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 * CONFIG_SYS_BAUDRATE_TABLE defines values that can be selected in u-boot command
43 #define CONFIG_SYS_UART_PORT (0)
46 * set "#if 0" to "#if 1" if (Hardware)-WATCHDOG should be enabled & change
47 * timeout acc. to your needs
48 * #define CONFIG_WATCHDOG_TIMEOUT x , x is timeout in milliseconds, e. g. 10000
54 #define CONFIG_WATCHDOG_TIMEOUT 10000 /* timeout in milliseconds */
58 * CONFIG_MONITOR_IS_IN_RAM defines if u-boot is started from a different
59 * bootloader residing in flash ('chainloading'); if you want to use
60 * chainloading or want to compile a u-boot binary that can be loaded into
63 * You will need a first stage bootloader then, e. g. colilo or a working BDM
64 * cable (Background Debug Mode)
66 * Setting #if 0: u-boot will start from flash and relocate itself to RAM
68 * Please do not forget to modify the setting of CONFIG_SYS_TEXT_BASE
69 * in board/cobra5272/config.mk accordingly (#if 0: 0xffe00000; #if 1: 0x20000)
75 #define CONFIG_MONITOR_IS_IN_RAM /* monitor is started from a preloader */
