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

      Fix all linker script to handle all rodata sections · f62fb999
      Trent Piepho 提交于
      A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
      which needs to be added the the linker script.  Instead of just adding this
      one section, we use a wildcard ".rodata*" to get all rodata linker section
      gcc has now and might add in the future.
      
      However, '*(.rodata*)' by itself will result in sub-optimal section
      ordering.  The sections will be sorted by object file, which causes extra
      padding between the unaligned rodata.str.1.1 of one object file and the
      aligned rodata of the next object file.  This is easy to fix by using the
      SORT_BY_ALIGNMENT command.
      
      This patch has not be tested one most of the boards modified.  Some boards
      have a linker script that looks something like this:
      
      *(.text)
      . = ALIGN(16);
      *(.rodata)
      *(.rodata.str1.4)
      *(.eh_frame)
      
      I change this to:
      
      *(.text)
      . = ALIGN(16);
      *(.eh_frame)
      *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
      
      This means the start of rodata will no longer be 16 bytes aligned.
      However, the boundary between text and rodata/eh_frame is still aligned to
      16 bytes, which is what I think the real purpose of the ALIGN call is.

      Change initdram() return type to phys_size_t · 9973e3c6
      Becky Bruce 提交于
      This patch changes the return type of initdram() from long int to phys_size_t.
      This is required for a couple of reasons: long int limits the amount of dram
      to 2GB, and u-boot in general is moving over to phys_size_t to represent the
      size of physical memory.  phys_size_t is defined as an unsigned long on almost
      all current platforms.
      
      This patch *only* changes the return type of the initdram function (in
      include/common.h, as well as in each board's implementation of initdram).  It
      does not actually modify the code inside the function on any of the platforms;
      platforms which wish to support more than 2GB of DRAM will need to modify
      their initdram() function code.
      
      Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
      MPC8641HPCN.

      Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections · 64134f01
      Wolfgang Denk 提交于
      With recent toolchain versions, some boards would not build because
      or errors like this one (here for ocotea board when building with
      ELDK 4.2 beta):
      ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
      
      For many boards, the .bss section is big enough that it wraps around
      at the end of the address space (0xFFFFFFFF), so the problem will not
      be visible unless you use a 64 bit tool chain for development. On
      some boards however, changes to the code size (due to different
      optimizations) we bail out with section overlaps like above.
      
      The fix is to add the NOLOAD attribute to the .bss and .sbss
      sections, telling the linker that .bss does not consume any space in
      the image.

      Add support for a saving build objects in a separate directory. · f9328639
      Marian Balakowicz 提交于
      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.
