2013-03-12TMU: Add TMU support in dtt commandAkshay Saraswat
Add generic TMU support alongwith i2c sensors in dtt command to enable temperature reading in cases where TMU is present along-with/instead-of i2c sensors.

2011-10-22hwmon: Provide dtt_init()Dirk Eibach
Our boards rely on dtt for initialization of fan hardware. dtt_init() was implemented to be called form board specific code. Signed-off-by: Dirk Eibach <eibach@gdsys.de> Acked-by: Heiko Schocher <hs@denx.de> Tested-by: Heiko Schocher <hs@denx.de>
2011-08-04hwmon: do not init sensors on startupHeiko Schocher
The U-Boot Design Principles[1] clearly say: Initialize devices only when they are needed within U-Boot, i.e. don't initialize the Ethernet interface(s) unless U-Boot performs a download over Ethernet; don't initialize any IDE or USB devices unless U-Boot actually tries to load files from these, etc. (and don't forget to shut down these devices after using them - otherwise nasty things may happen when you try to boot your OS). So, do not initialize and read the sensors on startup. Signed-off-by: Heiko Schocher <hs@denx.de> cc: Wolfgang Denk <wd@denx.de> cc: Holger Brunck <holger.brunck@keymile.com>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

2009-06-12General help message cleanupWolfgang Denk
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 <wd@denx.de>
2009-01-28Command usage cleanupPeter Tyser
Remove command name from all command "usage" fields and update common/command.c to display "name - usage" instead of just "usage". Also remove newlines from command usage fields. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

2007-07-04common/cmd_[a-f]* : Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).Jon Loeliger
This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger <jdl@freescale.com>
2007-02-20[PATCH] I2C: Add support for multiple I2C busses for RTC & DTTStefan Roese
This patch switches to the desired I2C bus when the date/dtt commands are called. This can be configured using the CFG_RTC_BUS_NUM and/or CFG_DTT_BUS_NUM defines. Signed-off-by: Stefan Roese <sr@denx.de>
