powerpc, 5xxx, 512x: remove support for mpc5xxx and mpc512x

2017-06-16T14:14:55+00:00

There was for long time no activity in the mpx5xxx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in mpc5xxx,
so remove it.

fdt: Move fdt_fixup_ethernet to a common place

2017-05-01T13:11:59+00:00

With 3f66149d9fb4 we no longer have a common call fdt_fixup_ethernet.
This was fine to do on PowerPC as they largely had calls already in
ft_cpu_fixup.  On ARM however we largely relied on this call.  Rather
than introduce a large number of changes to ft_cpu_fixup /
ft_board_fixup we recognize that this is a common enough call that we
should be doing it in a central location.  Do it early enough that we
can do any further updates in ft_cpu_fixup / ft_board_fixup.

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

2010-07-04T21:55:42+00:00

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 arch/ppc to arch/powerpc

2010-04-21T21:42:38+00:00

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.
