From a89c33db96a1e55319a286dd4c3c05ca64ac6bfd Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sun, 24 May 2009 17:06:54 +0200 Subject: General help message cleanup Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk --- board/amcc/taihu/lcd.c | 16 ++++++++-------- board/amcc/taihu/taihu.c | 8 ++++---- board/amcc/taihu/update.c | 4 ++-- 3 files changed, 14 insertions(+), 14 deletions(-) (limited to 'board/amcc/taihu') diff --git a/board/amcc/taihu/lcd.c b/board/amcc/taihu/lcd.c index 6b68f33..c3dc983 100644 --- a/board/amcc/taihu/lcd.c +++ b/board/amcc/taihu/lcd.c @@ -233,25 +233,25 @@ static int do_lcd_cur (cmd_tbl_t * cmdtp, int flag, int argc, char *argv[]) U_BOOT_CMD( lcd_cls, 1, 1, do_lcd_clear, "lcd clear display", - NULL - ); + "" +); U_BOOT_CMD( lcd_puts, 2, 1, do_lcd_puts, "display string on lcd", - " - to be displayed\n" - ); + " - to be displayed" +); U_BOOT_CMD( lcd_putc, 2, 1, do_lcd_putc, "display char on lcd", - " - to be displayed\n" - ); + " - to be displayed" +); U_BOOT_CMD( lcd_cur, 3, 1, do_lcd_cur, "shift cursor on lcd", " - shift cursor on lcd times, direction is \n" " - 0..31\n" - " - 0=backward 1=forward\n" - ); + " - 0=backward 1=forward" +); diff --git a/board/amcc/taihu/taihu.c b/board/amcc/taihu/taihu.c index 669429b..d8806ac 100644 --- a/board/amcc/taihu/taihu.c +++ b/board/amcc/taihu/taihu.c @@ -94,8 +94,8 @@ static int do_sw_stat(cmd_tbl_t* cmd_tp, int flags, int argc, char *argv[]) U_BOOT_CMD ( sw2_stat, 1, 1, do_sw_stat, "show status of switch 2", - NULL - ); + "" +); static int do_led_ctl(cmd_tbl_t* cmd_tp, int flags, int argc, char *argv[]) { @@ -134,8 +134,8 @@ U_BOOT_CMD ( led_ctl, 3, 1, do_led_ctl, "make led 1 or 2 on or off", " - make led on/off,\n" - "\tled_no is 1 or 2\t" - ); + "\tled_no is 1 or 2" +); #define SPI_CS_GPIO0 0 #define SPI_SCLK_GPIO14 14 diff --git a/board/amcc/taihu/update.c b/board/amcc/taihu/update.c index 8e96905..f9c31b3 100644 --- a/board/amcc/taihu/update.c +++ b/board/amcc/taihu/update.c @@ -128,5 +128,5 @@ static int update_boot_eeprom(cmd_tbl_t* cmdtp, int flag, int argc, char *argv[] U_BOOT_CMD ( update_boot_eeprom, 1, 1, update_boot_eeprom, "update boot eeprom content", - NULL - ); + "" +); -- cgit v1.1
