927d2cea6b mpc52xx, digsy_mtc_rev5: Fix Linux crash, if no Flash in bank 2
If no Flash is connected to cs1, Linux crashes, because
reg entries are not correct adapted.

Following fix is needed:
- swap base addresses in CONFIG_SYS_FLASH_BANKS_LIST, as
  flash bank 1 is on chipselect 0 and flash bank 2 on
  chipselect 1
- call fdt_fixup_nor_flash_size() from ft_board_setup()

466f0137e8 mpc5200, digsy_mtc: add support for rev5 board version
difference to previous board version:
- M29W128GH flash from Numonyx
- SDRAM ISSI IS45S16800 (Option A2 105°C)
- rev5 uses RTC RV-3029-C2
- update cs0 and cs1 baseaddr and length
  depending on the detected flash size.
- added Werner Pfister <Pfister_Werner@intercontrol.de>
  as maintainer for the digsy board variants
- As the M29W128GH needs a special flash_cmd_reset()
  document that in the new file doc/README.cfi.
- move "#endif /* CONFIG_CMD_IDE */" to the right place
- remove LOWBOOT config option for digsy_mtc and digsy_mtc_rev5
  boards
- change doc/README.cfi as Stefan Roese suggested

6d8962e814 Switch from archive libraries to partial linking
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.

1211a46485 config.mk cleanup: drop "-I$(TOPDIR)/board" entries
After the recent cleanups, a number of config.mk files consist only of
a "PLATFORM_CPPFLAGS += -I$(TOPDIR)/board" entry whih is not needed.
Remove such entries.  In most cases, that means that the whole
config.mk file can be removed.

2ae1824196 Makefile: move all Power Architecture boards into boards.cfg
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.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
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.

47e26b1bf9 cmd_usage(): simplify return code handling
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.

54841ab50c 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) {
			...
