      Handle most LDSCRIPT setting centrally · 83b7e2a7
      Scott Wood authored
      Currently, some linker scripts are found by common code in config.mk.
      Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
      sometimes in arch config.mk and sometimes in board config.mk.  Some
      are found using an arch-specific rule for looking in CPUDIR, etc.
      
      Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
      when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
      that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.
      
      Replace all of this -- except for a handful of boards that are actually
      selecting a linker script in a unique way -- with centralized ldscript
      finding.
      
      If board code specifies LDSCRIPT, that will be used.
      Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.
      
      If neither of these are specified, then the central config.mk will
      check for the existence of the following, in order:
      
      $(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
      $(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
      $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
      $(TOPDIR)/$(CPUDIR)/u-boot.lds
      
      Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
      were dead code, because they were overridden by a CPUDIR u-boot.lds under
      the old powerpc rules.  These boards' own u-boot.lds have bitrotted and
      no longer work -- these lds files have been removed.

      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.

      ppc: Enable full relocation to RAM · 85829017
      Peter Tyser authored
      The following changes allow U-Boot to fully relocate from flash to
      RAM:
       - Remove linker scripts' .fixup sections from the .text section
       - Add -mrelocatable to PLATFORM_RELFLAGS for all boards
       - Define CONFIG_RELOC_FIXUP_WORKS for all boards
      
      Previously, U-Boot would partially relocate, but statically initialized
      pointers needed to be manually relocated.

      Fix all linker script to handle all rodata sections · f62fb999
      Trent Piepho authored
      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 authored
      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.

      Big white-space cleanup. · 53677ef1
      Wolfgang Denk authored
      This commit gets rid of a huge amount of silly white-space issues.
      Especially, all sequences of SPACEs followed by TAB characters get
      removed (unless they appear in print statements).
      
      Also remove all embedded "vim:" and "vi:" statements which hide
      indentation problems.

      Fix config files for out-of-tree building · cda2a4a9
      Wolfgang Denk authored
      Several board/<...>/config.mk files include dynamically built (by
      the Makefile) config files but used the wrong file name of
      	$(TOPDIR)/board/$(BOARDDIR)/config.tmp
      instead if the correct
      	$(OBJTREE)/board/$(BOARDDIR)/config.tmp
      
      The bug is nasty because the build result is correct for the (normal)
      in-tree builds, and because 'sinclude' is used no errors get raised
      even for out-of-tree build tests. But out-of-tree builds use an
      incomplete and thus usually incorrect configuration...

      Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections · 64134f01
      Wolfgang Denk authored
      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.
