  • 1df99080c   powerpc/mpc8349: Use generic mpc85xx DDR driver ... Browse Code »

    MPC8349 has been using mpc85xx DDR driver through a symbolic link to
    mpc85xx_ddr_gen2.c. After consolidating the drivers to a single set
    under driver/ddr/fsl/, the link is replaced by referring driver
    directly. We now can simply enable the macro and use the driver.
    Other mpc83xx SoCs still use their own driver.

  • 842033e69   pci: introduce CONFIG_PCI_INDIRECT_BRIDGE option ... Browse Code »

    The pci_indirect.c file is always compiled when
    CONFIG_PCI is defined although the indirect PCI
    bridge support is not needed by every board.

    Introduce a new CONFIG_PCI_INDIRECT_BRIDGE
    config option and only compile indirect PCI
    bridge support if this options is enabled.

    Also add the new option into the configuration
    files of the boards which needs that.

    Compile tested for powerpc, x86, arm and nds32.
    MAKEALL results:

    extention of commit 3b6b256 "powerpc/mpc83xx: increment
    malloc heap size for the MPC832x MDS boards" to all other
    mpc83xx based boards. It fixes "Unable to save the rest

  • 25ddd1fb0   Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value ... Browse Code »

    CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
    being able to use "sizeof(struct global_data)" in assembler files.
    Recent experience has shown that manual synchronization is not
    reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
    GENERATED_GBL_DATA_SIZE which gets automatically generated by the
    asm-offsets tool. In the result, all definitions of this value can be
    deleted from the board config files. We have to make sure that all
    files that reference such data include the new file.

    No other changes have been done yet, but it is obvious that similar
    changes / simplifications can be done for other, related macro
    definitions as well.

  • 553f09823   Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZE ... Browse Code »

    CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be
    some end address; to make the meaning more clear we rename it into
    CONFIG_SYS_INIT_RAM_SIZE

    No other code changes are performed in this patch, only minor editing
    of white space (due to the changed length) and the comments was done,
    where noticed.

    Note that the code for the PATI and cmi_mpc5xx board configurations
    looks seriously broken. Last known maintainers on Cc:

  • d98b0523c   powerpc: Cleanup BOOTFLAG_* references ... Browse Code »
    29

    Now that warm booting is not supported, there isn't a need for the
    BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them.

    Note that this change makes the board info bd_bootflags field useless.
    It will always be set to 0, but we leave it around so that we don't
    break the board info structure that some OSes are expecting to be passed
    from U-Boot.

    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

  • 14d0a02a1   Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE ... Browse Code »

    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.

  • 9f530d59e   e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernels ... Browse Code »

    Newer Linux kernels can overrun the initial memory window used for
    booting with their BSS area. When this happens, they overwrite the FDT
    and silently fail to boot.

    On e300 CPUs, the Linux kernel uses an initial BAT covering the first
    256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase
    the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value
    allowed by Linux. This will allow very large kernels to boot.

    also tested on an 8323ERDB.

    v2: also remove the delayed icache enablement assumption in arch ppc's
    board.c, and add a CONFIG_MPC83xx define in the ITX config file for
    consistency (even though it was already being defined in 83xx'
    config.mk).

  • c7190f028   mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields ... Browse Code »

    some LCRR bits are not documented throughout the 83xx family RMs.
    New board porters copying similar board configurations might omit
    setting e.g., DBYP since it was not documented in their SoC's RM.

    Prevent them bricking their board by retaining power on reset values
    in bit fields that the board porter doesn't explicitly configure
    via CONFIG_SYS__ assignments in the board
    config file.

    also move LCRR assignment to cpu_init_r[am] to help ensure no
    transactions are being executed via the local bus while CLKDIV is being
    modified.

    also start to use i/o accessors.
