  • The top level Makefile does not do any recursion into subdirs when
    cleaning, so these clean/distclean targets in random arch/board dirs
    never get used. Punt them all.

    MAKEALL didn't report any errors related to this that I could see.

  • A large number of boards incorrectly used getenv() in their board init
    code running before relocation. In some cases this caused U-Boot to
    hang when certain environment variables grew too long.
    Fix the code to use getenv_r().

  • 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.

  • Clean up Makefile, and drop a lot of the config.mk files on the way.

    We now also automatically pick all boards that are listed in
    boards.cfg (and with all configurations), so we can drop the redundant
    entries from MAKEALL to avoid building these twice.

  • 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.

  • 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.

  • 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.

  • Most of the bss initialization loop increments 4 bytes
    at a time. And the loop end is checked for an 'equal'
    condition. Make the bss end address aligned by 4, so
    that the loop will end as expected.

  • 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.
