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 * CFG_HZ gives unit: 1000 -> 1 Hz ^= 1000 ms
61 #define CFG_CLK 66000000
62 #define CFG_SDRAM_SIZE 16 /* SDRAM size in MB */
65 * Enable use of Ethernet
72 * Define baudrate for UART1 (console output, tftp, ...)
73 * default value of CONFIG_BAUDRATE for Sentec board: 19200 baud
74 * CFG_BAUDRATE_TABLE defines values that can be selected in u-boot command
79 #define CONFIG_BAUDRATE 19200
80 #define CFG_BAUDRATE_TABLE { 9600 , 19200 , 38400 , 57600, 115200 }
83 * set "#if 0" to "#if 1" if (Hardware)-WATCHDOG should be enabled & change
84 * timeout acc. to your needs
85 * #define CONFIG_WATCHDOG_TIMEOUT x , x is timeout in milliseconds, e. g. 10000
91 #define CONFIG_WATCHDOG
92 #define CONFIG_WATCHDOG_TIMEOUT 10000 /* timeout in milliseconds */
96 * CONFIG_MONITOR_IS_IN_RAM defines if u-boot is started from a different
97 * bootloader residing in flash ('chainloading'); if you want to use
98 * chainloading or want to compile a u-boot binary that can be loaded into
101 * You will need a first stage bootloader then, e. g. colilo or a working BDM
102 * cable (Background Debug Mode)
104 * Setting #if 0: u-boot will start from flash and relocate itself to RAM
106 * Please do not forget to modify the setting of TEXT_BASE
107 * in board/cobra5272/config.mk accordingly (#if 0: 0xffe00000; #if 1: 0x20000)
113 #define CONFIG_MONITOR_IS_IN_RAM /* monitor is started from a preloader */
