2017-06-12powerpc, 8xx: remove support for 8xxHeiko Schocher
There was for long time no activity in the 8xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 8xx, so remove it (with a heavy heart, knowing that I remove here the root of U-Boot). Signed-off-by: Heiko Schocher <hs@denx.de>

2011-05-12Fix a few gcc warnings.Joakim Tjernlund
Noticed while building all of mpc8xx. Also constify usage string in timer.c Warnings fixed are: timer.c: In function 'timer': timer.c:189: warning: format not a string literal and no format arguments timer.c:258: warning: format not a string literal and no format arguments atm.c: In function 'atmUnload': atm.c:99: warning: array subscript is above array bounds atm.c: In function 'atmLoad': atm.c:65: warning: array subscript is above array bounds codec.c: In function 'codsp_write_pop_int': codec.c:678: warning: array subscript is above array bounds codec.c: In function 'codsp_write_cop_short': codec.c:585: warning: array subscript is above array bounds codec.c: In function 'codsp_write_sop_int': codec.c:512: warning: array subscript is above array bounds Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
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) { ...
