24 #ifndef _CONFIG_COBRA5272_H

29 * possible values for Sentec board: only Coldfire M5272 processor supported
30 * (please do not change)
34 #define CONFIG_MCF52x2 /* define processor family */
35 #define CONFIG_M5272 /* define processor type */
38 * Defines processor clock - important for correct timings concerning serial
40 * CONFIG_SYS_HZ gives unit: 1000 -> 1 Hz ^= 1000 ms
44 #define CONFIG_SYS_HZ 1000
45 #define CONFIG_SYS_CLK 66000000
46 #define CONFIG_SYS_SDRAM_SIZE 16 /* SDRAM size in MB */
49 * Enable use of Ethernet
54 /* Enable Dma Timer */
58 * Define baudrate for UART1 (console output, tftp, ...)
59 * default value of CONFIG_BAUDRATE for Sentec board: 19200 baud
60 * CONFIG_SYS_BAUDRATE_TABLE defines values that can be selected in u-boot command
65 #define CONFIG_MCFUART
66 #define CONFIG_SYS_UART_PORT (0)
67 #define CONFIG_BAUDRATE 19200
70 * set "#if 0" to "#if 1" if (Hardware)-WATCHDOG should be enabled & change
71 * timeout acc. to your needs
72 * #define CONFIG_WATCHDOG_TIMEOUT x , x is timeout in milliseconds, e. g. 10000
78 #define CONFIG_WATCHDOG
79 #define CONFIG_WATCHDOG_TIMEOUT 10000 /* timeout in milliseconds */
83 * CONFIG_MONITOR_IS_IN_RAM defines if u-boot is started from a different
84 * bootloader residing in flash ('chainloading'); if you want to use
85 * chainloading or want to compile a u-boot binary that can be loaded into
88 * You will need a first stage bootloader then, e. g. colilo or a working BDM
89 * cable (Background Debug Mode)
91 * Setting #if 0: u-boot will start from flash and relocate itself to RAM
93 * Please do not forget to modify the setting of CONFIG_SYS_TEXT_BASE
94 * in board/cobra5272/config.mk accordingly (#if 0: 0xffe00000; #if 1: 0x20000)
100 #define CONFIG_MONITOR_IS_IN_RAM /* monitor is started from a preloader */
