2011-08-29Fix compiler warnings generated by gcc 4.6.Vadim Bendebury
The newer compiler version is more thorough in detecting code inconsistencies, and reports warnings in many cases when building u-boot for kaen and alex. This change modifies the code to get rid of the warnings. There supposed to be no logical changes, so no testing other than building the system is being done. The files not yet upstreamed are excluded and will be submitted separately.

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) { ...

2009-07-25video: move extern declarations from C to headersAlessandro Rubini
This moves some extern declaration from lcd.c to lcd.h, removing unneeded ifdef around a pair of them. Additionally, since gunzip_bmp() was declared static in cmd_bmp.c but extern in lcd.c, I removed the static. The extra "#include <lcd.h>" in cmd_bmp.c is added to ensure the header is consistent with the source. This has been compile-tested on both ARM (at91 boards) and PowerPC (HH405_config, TQM823L_LCD_config, mcc200_config), to test all use combinations.

2009-07-18stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD
So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

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.
