      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.

      API for external applications. · 500856eb
      Rafal Jaworowski authored
      This is an API for external (standalone) applications running on top of
      U-Boot, and is meant to be more extensible and robust than the existing
      jumptable mechanism. It is similar to UNIX syscall approach. See api/README
      for more details.
      
      Included is the demo application using this new framework (api_examples).
      
      Please note this is still an experimental feature, and is turned off by
      default.

      Add support for a saving build objects in a separate directory. · f9328639
      Marian Balakowicz authored
      Modifications are based on the linux kernel approach and
      support two use cases:
      
        1) Add O= to the make command line
        'make O=/tmp/build all'
      
        2) Set environement variable BUILD_DIR to point to the desired location
        'export BUILD_DIR=/tmp/build'
        'make'
      
      The second approach can also be used with a MAKEALL script
      'export BUILD_DIR=/tmp/build'
      './MAKEALL'
      
      Command line 'O=' setting overrides BUILD_DIR environent variable.
      
      When none of the above methods is used the local build is performed and
      the object files are placed in the source directory.
