2010-11-28do_bootm: unify duplicate prototypesMike Frysinger
The duplication of the do_bootm prototype has gotten out of hand, and they're pretty much all outdated (wrt constness). Unify them all in command.h. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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) { ...

2007-08-03cm1_qp1 -> cm5200: single U-Boot image for modules from the cm5200 family.Bartlomiej Sieka
Add the ability for modules from the Schindler cm5200 family to use a single U-Boot image: - rename cm1_qp1 to cm5200 - add run-time module detection - parametrize SDRAM configuration according to the module we are running on Few minor, board-specific fixes included in this patch: - better MAC address handling - updated default environment ('update' command uses +{filesize} now) - improved error messages in the auto-update code - allow booting U-Boot from RAM (CFG_RAMBOOT) Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Piotr Kruszynski <ppk@semihalf.com> Signed-off-by: Bartlomiej Sieka <tur@semihalf.com>
