Blackfin: new spibootldr command Newer Blackfin parts can an on-chip ROM that can boot LDRs over SPI flashes, so add a new 'spibootldr' command to take advantage of it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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) { ...

various cmd_* files: fixed layout a little bit Most of the files have U_BOOT_CMD on a separate line, but a few didn't and had the first line on the same line as U_BOOT_CMD. This changes these files by adding a line break and a tab Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com>
