ppc: Remove PCIPPC2 and PCIPPC6 boards

2013-03-11T21:00:28+00:00

These boards seem to be unmaintained for quite some time. So lets
remove support for them completely. This also cleans up some
common drivers/files.

serial: Use default_serial_puts() in drivers

2012-10-17T14:55:50+00:00

Replace the in-place ad-hoc implementation of serial_puts() within
the drivers with default_serial_puts() call. This cuts down on the
code duplication quite a bit.

serial: Remove CONFIG_SERIAL_MULTI from serial drivers

2012-10-15T18:53:58+00:00

Remove the support for not-CONFIG_SERIAL_MULTI part from serial
port drivers and some board files. Since CONFIG_SERIAL_MULTI is
now enabled by default, that part is a dead code. Remove it.

serial: powerpc: Implement CONFIG_SERIAL_MULTI into sconsole serial driver

2012-10-15T18:53:53+00:00

Implement support for CONFIG_SERIAL_MULTI into sconsole serial driver.
This driver was so far only usable directly, but this patch also adds
support for the multi method. This allows using more than one serial
driver alongside the sconsole driver. Also, add a weak implementation
of default_serial_console() returning this driver.

Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Makefile: move all Power Architecture boards into boards.cfg

2010-10-18T20:12:04+00:00

Clean up Makefile, and drop a lot of the config.mk files on the way.

We now also automatically pick all boards that are listed in
boards.cfg (and with all configurations), so we can drop the redundant
entries from MAKEALL to avoid building these twice.

Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

2010-10-18T20:07:10+00:00

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

cmd_usage(): simplify return code handling

2010-07-24T18:43:57+00:00

Lots of code use this construct:

	cmd_usage(cmdtp);
	return 1;

Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by

	return cmd_usage(cmdtp);

This fixes a few places with incorrect return code handling, too.

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) {
			...
