* powerpc: do not fixup NULL ptrsJoakim Tjernlund2010-10-181-1/+3
| | | | | | | | | | | | | | The fixup routine must not fixup NULL pointers. Problem can be seen by char *testfun(void) __attribute__((weak)); char *(*myfun)(void) = testfun; Then add printf("myfun:%p, &myfun:%p\n", myfun, &myfun); before relocation and after relocation. myfun should be NULL in both cases but it is not.

* powerpc: Cleanup BOOTFLAG_* referencesPeter Tyser2010-10-181-0/+1
| | | | | | | | | | | | Now that warm booting is not supported, there isn't a need for the BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them. Note that this change makes the board info bd_bootflags field useless. It will always be set to 0, but we leave it around so that we don't break the board info structure that some OSes are expecting to be passed from U-Boot.

* powerpc: Remove warm reset entry pointPeter Tyser2010-10-121-15/+1

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* Remove AmigaOneG3SE boardWolfgang Denk2010-06-235-27/+8
| | | | | | | | | | The AmigaOneG3SE board has been orphaned or a very long time, and broken for more than 12 releases resp. more than 3 years. As nobody seems to be interested any more in this stuff we may as well ged rid of it, especially as it clutters many areas of the code so it is a continuous pain for all kinds of ongoing work.

* Get rid of bogus CONFIG_SYS_BUS_HZ and CONFIG_SYS_CONFIG_BUS_CLK definitionsWolfgang Denk2010-06-231-8/+6
| | | | | | | | | | | | | | | CONFIG_SYS_BUS_HZ has not really been used anywhere except to be redined as CONFIG_SYS_BUS_CLK; in addition, the mpc7448hpc2 had the bogus CONFIG_SYS_CONFIG_BUS_CLK setting which duplicated the funtionality. Change all this to use CONFIG_SYS_BUS_CLK consistently.

* Move arch/ppc to arch/powerpcStefan Roese2010-04-2111-0/+2485
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.
