Use #define CONFIG_IIM to turn on the clock for this module use #define CONFIG_CMD_FUSE to add fusebox commands. Fusebox commands include the ability to read the status, read the register cache, override the register cache, program the fuses and sense them.

Modified to use u-boot's HUSH parser. Cleanup on environment settings. Removed compiler warning by defining CONFIG_SYS_CS0_* Dependencies: Added the use of CONFIG_SYS_MCF_SYNCR for clock multiplier. This depends on a patch to include/asm-m68k/m5271.h that defines the multiplier and divider ratios. Removed the definition of CONFIG_SYS_FECI2C. This depends on a patch that removes the use of it in cpu/mcf52x2/cpu_init.c Signed-off-by: Richard Retanubun --- include/configs/M5271EVB.h | 40 ++++++++++++++++++++++++++++++---------- 1 file changed, 30 insertions(+), 10 deletions(-) (limited to 'include/configs') diff --git a/include/configs/M5271EVB.h b/include/configs/M5271EVB.h index 7ddeb550b61..50b3ab28084 100644 --- a/include/configs/M5271EVB.h +++ b/include/configs/M5271EVB.h @@ -82,7 +82,10 @@ #define CONFIG_CMD_MISC #undef CONFIG_CMD_LOADS -#undef CONFIG_CMD_LOADB +#define CONFIG_CMD_LOADB +#define CONFIG_CMDLINE_EDITING 1 /* enables command line history */ +#define CONFIG_SYS_HUSH_PARSER /* Use the HUSH parser */ +#define CONFIG_SYS_PROMPT_HUSH_PS2 "> " #define CONFIG_MCFFEC #ifdef CONFIG_MCFFEC @@ -116,7 +119,7 @@ #define CONFIG_SYS_I2C_OFFSET 0x00000300 #define CONFIG_SYS_IMMR CONFIG_SYS_MBAR -#define CONFIG_BOOTDELAY 1 /* autoboot after 5 seconds */ +#define CONFIG_BOOTDELAY 1 /* autoboot after 1 seconds */ #define CONFIG_BOOTFILE "u-boot.bin" #ifdef CONFIG_MCFFEC # define CONFIG_NET_RETRY_COUNT 5 @@ -128,16 +131,16 @@ # define CONFIG_OVERWRITE_ETHADDR_ONCE #endif /* FEC_ENET */ -#define CONFIG_HOSTNAME M5235EVB +#define CONFIG_HOSTNAME M5271EVB #define CONFIG_EXTRA_ENV_SETTINGS \ "netdev=eth0\0" \ "loadaddr=10000\0" \ - "u-boot=u-boot.bin\0" \ - "load=tftp ${loadaddr) ${u-boot}\0" \ + "uboot=u-boot.bin\0" \ + "load=tftp $loadaddr $uboot\0" \ "upd=run load; run prog\0" \ - "prog=prot off ffe00000 ffe2ffff;" \ - "era ffe00000 ffe2ffff;" \ - "cp.b ${loadaddr} 0 ${filesize};" \ + "prog=prot off ffe00000 ffe3ffff;" \ + "era ffe00000 ffe3ffff;" \ + "cp.b $loadaddr ffe00000 $filesize;" \ "save\0" \ "" @@ -159,7 +162,17 @@ #define CONFIG_SYS_MEMTEST_END 0x380000 #define CONFIG_SYS_HZ 1000000 + +/* Clock configuration + * The external oscillator is a 25.000 MHz + * CONFIG_SYS_CLK for ColdFire V2 sets cpu_clk (not bus_clk) + * bus_clk = (cpu_clk/2) (fixed ratio) + * + * If CONFIG_SYS_CLK is changed. the CONFIG_SYS_MCF_SYNCR must be updated to + * match the new clock speed.
