20 * board/config.h - configuration options, board specific
24 #ifndef _CONFIG_COBRA5272_H
25 #define _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
43 #define CONFIG_SYS_CLK 66000000
44 #define CONFIG_SYS_SDRAM_SIZE 16 /* SDRAM size in MB */
47 * Enable use of Ethernet
52 /* Enable Dma Timer */
56 * Define baudrate for UART1 (console output, tftp, ...)
57 * default value of CONFIG_BAUDRATE for Sentec board: 19200 baud
58 * CONFIG_SYS_BAUDRATE_TABLE defines values that can be selected in u-boot command
63 #define CONFIG_MCFUART
64 #define CONFIG_SYS_UART_PORT (0)
65 #define CONFIG_BAUDRATE 19200
68 * set "#if 0" to "#if 1" if (Hardware)-WATCHDOG should be enabled & change
69 * timeout acc. to your needs
70 * #define CONFIG_WATCHDOG_TIMEOUT x , x is timeout in milliseconds, e. g. 10000
76 #define CONFIG_WATCHDOG
77 #define CONFIG_WATCHDOG_TIMEOUT 10000 /* timeout in milliseconds */
81 * CONFIG_MONITOR_IS_IN_RAM defines if u-boot is started from a different
82 * bootloader residing in flash ('chainloading'); if you want to use
83 * chainloading or want to compile a u-boot binary that can be loaded into
86 * You will need a first stage bootloader then, e. g. colilo or a working BDM
87 * cable (Background Debug Mode)
89 * Setting #if 0: u-boot will start from flash and relocate itself to RAM
91 * Please do not forget to modify the setting of CONFIG_SYS_TEXT_BASE
92 * in board/cobra5272/config.mk accordingly (#if 0: 0xffe00000; #if 1: 0x20000)
98 #define CONFIG_MONITOR_IS_IN_RAM /* monitor is started from a preloader */
