      Switch from archive libraries to partial linking · 6d8962e8
      Sebastien Carlier authored 
      
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.

      Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE · 14d0a02a
      Wolfgang Denk authored 
      
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.

      Make sure that argv[] argument pointers are not modified. · 54841ab5
      Wolfgang Denk authored 
      
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) {
			...

      Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>" · 61f2b38a
      Peter Tyser authored 
      
The appropriate include/asm-$ARCH directory should already by symlinked
to include/asm so using the whole "asm-$ARCH" path is unnecessary.

This change should also allow us to move the include/asm-$ARCH
directories into their appropriate lib/$ARCH/ directories.

      Rename lib_generic/ to lib/ · 78acc472
      Peter Tyser authored 
      
Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.

      Change directory-specific CFLAGS to use full path · 89f39e17
      Peter Tyser authored 
      
Previously, a specific file or directory could be compiled with custom
CFLAGS by adding a Makefile variable such as:
  CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c>
or
  CFLAGS_lib = <custom flags for lib directory>

This method breaks down once multiple files or directories share the
same path.  Eg FLAGS_fileA = <custom flags> would incorrectly result in
both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>.

This change allows finer grained control which we need once we move
lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/.  Without this
change all lib/ directories would share the same custom CFLAGS.

      General help message cleanup · a89c33db
      Wolfgang Denk authored 
      
Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt
