MIPS: bootm.c: add support for 'prep' and 'go' subcommands

2013-01-16T09:52:07Z

The bootm command supports subcommands since long time however those subcommands are not yet usable on MIPS. The patch is based on the ARM implementation, and it adds support for the 'prep' and 'go' subcommands only. Signed-off-by: Gabor Juhos Cc: Daniel Schwierzeck

MIPS: bootm.c: separate environment initialization

2013-01-16T09:52:07Z

Move the environment initialization code into a separate function. This make the code reusable for bootm subcommands. Signed-off-by: Gabor Juhos Cc: Daniel Schwierzeck

MIPS: bootm.c: separate linux jump code

2013-01-16T09:52:07Z

Move the actual jump code into a separate function. This make the code reusable for bootm subcommands. Signed-off-by: Gabor Juhos Cc: Daniel Schwierzeck

MIPS: bootm.c: use debug macro to print debug message

2013-01-16T09:52:07Z

The '## Transferring control ...' message is printed only if DEBUG is enabled. Get rid of the 'ifdef DEBUG' statement and use the debug macro instead. Signed-off-by: Gabor Juhos

bootstage: Replace show_boot_progress/error() with bootstage_...()

2012-03-18T20:41:39Z

These calls should not be made directly any more, since bootstage will call the show_boot_...() functions as needed. Signed-off-by: Simon Glass

bootstage: Make use of BOOTSTAGE_ID_RUN_OS in show_boot_progress()

2012-03-18T19:45:57Z

This changes the number 15 as used in boot_stage_progress() to use the new name provided for it. This is a separate patch because it touches so many files. Signed-off-by: Simon Glass Acked-by: Mike Frysinger

Make sure that argv[] argument pointers are not modified.

2010-07-04T21:55:42Z

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) { ...

Move lib_$ARCH directories to arch/$ARCH/lib

2010-04-13T07:13:03Z

Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser
