* fdt_support: delete force argument of fdt_initrd()Masahiro Yamada2014-06-19-1/+1
| | | | | | | | | | | | After all, we have realized "force" argument is completely useless. fdt_initrd() was always called with force = 1. We should always want to do the same thing (set appropriate value to the property) even if the property already exists.

* avr32/m68k/microblaze/nds32/nios2/openrisc/sh/sparc: fix do_bootm_linuxAndreas Bießmann2013-07-02-0/+6
| | | | | | | | | | | | Commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 broke bootm on avr32. It requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before calling it again with flag set to BOOTM_STATE_OS_GO. Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will require a complete refactoring later on.

* Clarify bootm OS argumentsSimon Glass2013-06-26-2/+2
| | | | | | | | | | | | | | At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>

* bootstage: Replace show_boot_progress/error() with bootstage_...()Simon Glass2012-03-18-1/+1
| | | | | | | These calls should not be made directly any more, since bootstage will call the show_boot_...() functions as needed. Signed-off-by: Simon Glass <sjg@chromium.org>

* FDT: only call boot_get_fdt from generic codeJohn Rigby2010-10-18-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | All arches except nios2 and microblaze call boot_get_fdt from bootm_start in common/cmd_bootm.c. Having nios2 and microblaze do so as well removes code from their respective do_bootm_linux routines and allows removal of a nasty ifdef from bootm_start. In the case where boot_get_fdt returns an error bootm_start returns and the platform specific do_bootm_linux routines will never get called. Also only check argv[3] for an fdt addr if argc > 3 first. This is already the case for nios2.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...
