  • a89988a6e   nios2: Add NIOS2_ARCH_REVISION to select between R1 and R2 ... Browse Code »

    Allow user to select between Nios2 R1 and R2. Since R1 and R2 are
    not binary compatible, we cannot have a single kernel binary and
    there is no point in having DT property for discerning these two.

  • 9fa78f63a   nios2: Add order-only DTC dependency to %.dtb target ... Browse Code »

    The dtc dependency is missing, thus dtc is not built before it's invoked,
    resulting in the following problem:

    linux-2.6$ make 10m50_defconfig && make 10m50_devboard.dtb
    [...]
    scripts/kconfig/conf --silentoldconfig Kconfig
    DTC arch/nios2/boot/10m50_devboard.dtb
    /bin/sh: 1: ./scripts/dtc/dtc: not found
    arch/nios2/boot/Makefile:52: recipe for target 'arch/nios2/boot/10m50_devboard.dtb' failed
    make[1]: *** [arch/nios2/boot/10m50_devboard.dtb] Error 127
    arch/nios2/Makefile:57: recipe for target '10m50_devboard.dtb' failed
    make: *** [10m50_devboard.dtb] Error 2

  • fb75a2bb5   nios2: Fix libgcc location detection ... Browse Code »

    The extra CFLAGS required for correct operation of the toolchain are not
    propagated into the libgcc detection code. In case of the compiler from
    poky sdk, these extra CFLAGS contain the location of compiler sysroot
    (the --sysroot= option) and without this option, the location of libgcc
    is not properly reported. Add the missing CFLAGS to address this issue.

  • d1e4ef042   nios2: enable "make defconfig" ... Browse Code »

    Running "make defconfig" currently fails for nios2:
    $ make ARCH=nios2 defconfig
    scripts/kconfig/conf --defconfig Kconfig
    ***
    *** Can't find default configuration "arch/nios2/defconfig"!
    ***
    make[1]: *** [defconfig] Error 1
    make: *** [defconfig] Error 2

    Add a definition for KBUILD_DEFCONFIG to the nios2's main Makefile to enable
    this make target.
