  • c9e1f5881   powerpc: p1010rdb: Enable p1010rdb to start from NAND/SD/SPI flash with SPL ... Browse Code »

    In the previous patches, we introduced the SPL/TPL fraamework.
    For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
    SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
    the DDR according to the SPD and loads the final uboot image into DDR, then
    jump to the DDR to begin execution.

    For NAND booting way, the nand SPL has size limitation on some board(e.g.
    P1010RDB), it can not be more than 8KB, we can call it "minimal SPL", So the
    dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
    loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
    and loads the final uboot image into DDR,then jump to the DDR to begin execution.

    This patch enabled SPL/TPL for P1010RDB to support starting from NAND/SD/SPI
    flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
    Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
    execute, so the section .resetvec is no longer needed.

    New hardware version cannot recognize the SD-Card
    because the SYS_NRESWARM, set as GPIO, does not
    guarantee the required reset time.
    Change the pin function back to enable the

    Schematic indicates GPIO5_7 is to be used for VTT regulator control
    rather than GPIO0_21 so modify enable_vtt_regulator to reflect this.
    Without this some boards will experience DDR3 corruption and fail to
    boot.

  • da4105dfc   am335x: Initial support for Silica Pengwyn board ... Browse Code »

    This patch add support for the Silica Pengwyn board [1]
    The board is based on a TI AM3354 CPU [2]
    All jumpers removed it will boot from the SDcard, the console is on
    UART1 accessible via the FDTI -> USB. The on board NAND flash is
    supported and can act as boot medium, depending on jumper settings.
    USB Host, USB Device and Ethernet are also provided but untested.

    Conflicts:

    These two conflicts arise from commit 0b2d3f20
    ("ARM: NET: Remove the IXP NPE ethernet driver") and are
    resolved by deleting the drivers/net/npe/Makefile file
    and removing the CONFIG_IXP4XX_NPE line from Makefile.

  • 5ab502cb8   dts: move device tree sources to arch/$(ARCH)/dts/ ... Browse Code »

    Unlike Linux Kernel, U-Boot historically had *.dts files under
    board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

    I think arch/$(ARCH)/dts dicretory is a better location
    to store both *.dts and *.dtsi files.

    For example, before this commit, board/xilinx/dts directory
    had both Microblaze dts (microblaze-generic.dts) and
    ARM dts (zynq-*.dts), which are totally unrelated.

    This commit moves *.dts to arch/$(ARCH)/dts/ directories,
    allowing us to describe nicely mutiple DTBs generation in the next commit.

  • b831bb36b   board: sandburst: delete FORCEBUILD ... Browse Code »

    We had switched to Kbuild, so we do not need to
    delete sandburst board files at every build.

    U-Boot conventional build system did not check the
    update of command line option, -DBUILDUSER.

    Kbuild can handle it nicely and re-builds object files
    when command line options are changed.
    (The file ".*.cmd" stores the information how the file
    was generated at the previous build.)

    This commit refactors cleaning targets such as
    clean, clobber, mrpropper, distclean
    with scripts/Makefile.clean.

    By using scripts/Makefile.clean, we can recursively descend
    into subdirectories and delete generated files there.

    We do not need add a big list of generated files
    to the "clean" target.

  • 6825a95b0   kbuild: use Linux Kernel build scripts ... Browse Code »

    Now we are ready to switch over to real Kbuild.

    This commit disables temporary scripts:
    scripts/{Makefile.build.tmp, Makefile.host.tmp}
    and enables real Kbuild scripts:
    scripts/{Makefile.build,Makefile.host,Makefile.lib}.

    This switch is triggered by the line in scripts/Kbuild.include
    -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
    +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

    We need to adjust some build scripts for U-Boot.
    But smaller amount of modification is preferable.

    Additionally, we need to fix compiler flags which are
    locally added or removed.

    In Kbuild, it is not allowed to change CFLAGS locally.
    Instead, ccflags-y, asflags-y, cppflags-y,
    CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
    are prepared for that purpose.

  • 9e4140329   kbuild: change out-of-tree build ... Browse Code »
    43

    This commit changes the working directory
    where the build process occurs.

    Before this commit, build process occurred under the source
    tree for both in-tree and out-of-tree build.

    That's why we needed to add $(obj) prefix to all generated
    files in makefiles like follows:
    $(obj)u-boot.bin: $(obj)u-boot

    Here, $(obj) is empty for in-tree build, whereas it points
    to the output directory for out-of-tree build.

    And our old build system changes the current working directory
    with "make -C " syntax when descending into the
    sub-directories.

    On the other hand, Kbuild uses a different idea
    to handle out-of-tree build and directory descending.

    The build process of Kbuild always occurs under the output tree.
    When "O=dir/to/store/output/files" is given, the build system
    changes the current working directory to that directory and
    restarts the make.

    Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj="
    syntax for descending into sub-directories.
    (We can write it like "make $(obj)=" with a shorthand.)
    This means the current working directory is always the top
    of the output directory.
