26 * Version: U-boot 1.0.0 - initial release for Sentec COBRA5272 board
28 * Author: Florian Schlote
30 * For a description of configuration options please refer also to the
31 * general u-boot-1.x.x/README file
36 * board/config.h - configuration options, board specific
40 #ifndef _CONFIG_COBRA5272_H
41 #define _CONFIG_COBRA5272_H
45 * possible values for Sentec board: only Coldfire M5272 processor supported
46 * (please do not change)
50 #define CONFIG_MCF52x2 /* define processor family */
51 #define CONFIG_M5272 /* define processor type */
54 * Defines processor clock - important for correct timings concerning serial
56 * CONFIG_SYS_HZ gives unit: 1000 -> 1 Hz ^= 1000 ms
60 #define CONFIG_SYS_HZ 1000
61 #define CONFIG_SYS_CLK 66000000
62 #define CONFIG_SYS_SDRAM_SIZE 16 /* SDRAM size in MB */
65 * Enable use of Ethernet
70 /* Enable Dma Timer */
74 * Define baudrate for UART1 (console output, tftp, ...)
75 * default value of CONFIG_BAUDRATE for Sentec board: 19200 baud
76 * CONFIG_SYS_BAUDRATE_TABLE defines values that can be selected in u-boot command
81 #define CONFIG_MCFUART
82 #define CONFIG_SYS_UART_PORT (0)
83 #define CONFIG_BAUDRATE 19200
84 #define CONFIG_SYS_BAUDRATE_TABLE { 9600 , 19200 , 38400 , 57600, 115200 }
87 * set "#if 0" to "#if 1" if (Hardware)-WATCHDOG should be enabled & change
88 * timeout acc. to your needs
89 * #define CONFIG_WATCHDOG_TIMEOUT x , x is timeout in milliseconds, e. g. 10000
95 #define CONFIG_WATCHDOG
96 #define CONFIG_WATCHDOG_TIMEOUT 10000 /* timeout in milliseconds */
100 * CONFIG_MONITOR_IS_IN_RAM defines if u-boot is started from a different
101 * bootloader residing in flash ('chainloading'); if you want to use
102 * chainloading or want to compile a u-boot binary that can be loaded into
105 * You will need a first stage bootloader then, e. g. colilo or a working BDM
106 * cable (Background Debug Mode)
108 * Setting #if 0: u-boot will start from flash and relocate itself to RAM
110 * Please do not forget to modify the setting of TEXT_BASE
111 * in board/cobra5272/config.mk accordingly (#if 0: 0xffe00000; #if 1: 0x20000)
117 #define CONFIG_MONITOR_IS_IN_RAM /* monitor is started from a preloader */
121 * Configuration for environment
122 * Environment is embedded in u-boot in the second sector of the flash
