2013-06-11powerpc: fix 8xx and 82xx type-punning warnings with GCC 4.7Scott Wood
C99's strict aliasing rules are insane to use in low-level code such as a bootloader, but as Wolfgang has rejected -fno-strict-aliasing in the past, add a union so that 16-bit accesses can be performed. Compile-tested only. Signed-off-by: Scott Wood <scottwood@freescale.com> Acked-by: Wolfgang Denk <wd@denx.de>
2013-02-08Clean up libfdt.h includesGerald Van Baren
The libfdt.h file is the definition file for libfdt. It is unnecessary to include other fdt header files (the necessary ones are pulled in by libfdt.h). Signed-off-by: Gerald Van Baren <gvb@unssw.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Stefan Roese <sr@denx.de>

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) { ...

2010-04-21Move arch/ppc to arch/powerpcStefan Roese
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
