      Add board MAINTAINERS files · 93d4334f
      Masahiro Yamada authored
      We have switched to Kconfig and the boards.cfg file is going to
      be removed. We have to retrieve the board status and maintainers
      information from it.
      
      The MAINTAINERS format as in Linux Kernel would be nice
      because we can crib the scripts/get_maintainer.pl script.
      
      After some discussion, we chose to put a MAINTAINERS file under each
      board directory, not the top-level one because we want to collect
      relevant information for a board into a single place.
      
      TODO:
      Modify get_maintainer.pl to scan multiple MAINTAINERS files.

      kconfig: add board Kconfig and defconfig files · dd84058d
      Masahiro Yamada authored
      This commit adds:
       - arch/${ARCH}/Kconfig
          provide a menu to select target boards
       - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
          set CONFIG macros to the appropriate values for each board
       - configs/${TARGET_BOARD}_defconfig
          default setting of each board
      
      (This commit was automatically generated by a conversion script
      based on boards.cfg)
      
      In Linux Kernel, defconfig files are located under
      arch/${ARCH}/configs/ directory.
      It works in Linux Kernel since ARCH is always given from the
      command line for cross compile.
      
      But in U-Boot, ARCH is not given from the command line.
      Which means we cannot know ARCH until the board configuration is done.
      That is why all the "*_defconfig" files should be gathered into a
      single directory ./configs/.

      SPDX: fix IBM-pibs license identifier · 1b387ef5
      Wolfgang Denk authored
      The SPDX License List version 1.19 now contains an official entry for
      the IBM-pibs license.  However, instead of our suggestion "ibm-pibs",
      the SPDX License List uses "IBM-pibs", with the following rationale:
      "The reason being that all other SPDX License List short identifiers
      tend towards using capital letters unless spelling a word.  I'd prefer
      to be consistent to this end".
      
      Change the license IDs to use the official name.

      SPDX-License-Identifier: convert PIBS licensed files · 46263f2d
      Wolfgang Denk authored
      This commit adapts the files that were derived from PIBS (PowerPC
      Initialization and Boot Software) codeto using SPDX License
      Identifiers.
      
      So far, SPDX has not assigned an official License ID for the PIBS
      license yet, so this should be considered preliminary.
      
      Note that the following files contained incorrect license information:
      
      	arch/powerpc/cpu/ppc4xx/4xx_uart.c
      	arch/powerpc/cpu/ppc4xx/start.S
      	arch/powerpc/include/asm/ppc440.h
      
      These files included, in addition to the GPL-2.0 / ibm-pibs dual
      license as inherited from PIBS, a GPL-2.0+ license header which was
      obviously incorrect.  This has 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.

      Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE · 14d0a02a
      Wolfgang Denk authored
      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.

      ppc4xx: Big cleanup of PPC4xx defines · 297a6587
      Stefan Roese authored
      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.

      Dual-license IBM code contributions · 31773496
      Josh Boyer authored
      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.

      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.

      ppc4xx: Remove superfluous dram_init() call or replace it by initdram() · bbeff30c
      Stefan Roese authored
      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.

      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.

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