      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 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.
