Che-Liang Chiou	a2a5729fc1	api: export LCD device to external apps This patch exports LCD info-query and bitmap-rendering functions to external apps. This patch is tested on a Seaboard. Because the LCD driver is not yet upstreamed, the test was done in a local downstream repo. Signed-off-by: Che-Liang Chiou <clchiou@chromium.org>	14 years ago
Mike Frysinger	882b7d726f	do_reset: unify duplicate prototypes The duplication of the do_reset prototype has gotten out of hand, and they're not all in sync. Unify them all in command.h. Signed-off-by: Mike Frysinger <vapier@gentoo.org>	15 years ago
Wolfgang Denk	54841ab50c	Make sure that argv[] argument pointers are not modified. 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) { ...

Rafal Jaworowski	500856eb17	API for external applications. This is an API for external (standalone) applications running on top of U-Boot, and is meant to be more extensible and robust than the existing jumptable mechanism. It is similar to UNIX syscall approach. See api/README for more details. Included is the demo application using this new framework (api_examples). Please note this is still an experimental feature, and is turned off by default. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>	18 years ago
