  • 858290178   ppc: Enable full relocation to RAM ... Browse Code »

    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.

  • d1c3b2752   ppc4xx: Big cleanup of PPC4xx defines ... Browse Code »

    This patch cleans up multiple issues of the 4xx register (mostly
    DCR, SDR, CPR, etc) definitions:

    - Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
    - Change the defines to better match the names from the
    user's manuals (e.g. cprpllc -> CPR0_PLLC)
    - Removal of some unused defines

    Please test this patch intensive on your PPC4xx platform. Even though
    I tried not to break anything and tested successfully on multiple
    4xx AMCC platforms, testing on custom platforms is recommended.

  • 317734966   Dual-license IBM code contributions ... Browse Code »

    It was brought to our attention that U-Boot contains code derived from the
    IBM OpenBIOS source code originally provided with some of the older PowerPC
    4xx development boards. As a result, the original license of this code has
    been carried in the various files for a number of years in the U-Boot project.

    IBM is dual-licensing the IBM code contributions already present in U-Boot
    under either the terms of the GNU General Public License version 2, or the
    original code license already present.

  • f62fb9994   Fix all linker script to handle all rodata sections ... Browse Code »

    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.

  • 9b827cf17   Align end of bss by 4 bytes ... Browse Code »

    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.

  • 9973e3c61   Change initdram() return type to phys_size_t ... Browse Code »

    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.

  • bbeff30cb   ppc4xx: Remove superfluous dram_init() call or replace it by initdram() ... Browse Code »

    Historically the 405 U-Boot port had a dram_init() call in early init
    stage. This function was still called from start.S and most of the time
    coded in assembler. This is not needed anymore (since a long time) and
    boards should implement the common initdram() function in C instead.

    This patch now removed the dram_init() call from start.S and removes the
    empty implementations that are scattered through most of the 405 board
    ports. Some older board ports really implement this dram_init() though.
    These are:

    csb272
    csb472
    ERIC
    EXBITGEN
    W7OLMC
    W7OLMG

    I changed those boards to call this assembler dram_init() function now
    from their board specific initdram() instead. This *should* work, but please
    test again on those platforms. And it is perhaps a good idea that those
    boards use some common 405 SDRAM initialization code from cpu/ppc4xx at
    some time. So further patches welcome here.

  • 53677ef18   Big white-space cleanup. ... Browse Code »

    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.

  • 64134f011   Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections ... Browse Code »
    21

    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.

  • f93286397   Add support for a saving build objects in a separate directory. ... Browse Code »

    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.
