      net: drop !NET_MULTI code · e2a53458
      Mike Frysinger authored
      This is long over due.  All but two net drivers have been converted, but
      those have now been dropped.
      
      The only thing left to do is actually delete all references to NET_MULTI
      and code that is compiled when that is not defined.  So here we scrub the
      core code.

      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) {
      			...

      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.
