      [POWERPC] bootwrapper: Build multiple cuImages · 25431333
      Grant Likely 提交于
      Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image
      with a fdt blob which means for any given configuration only one dts
      file can be selected and so support for only one board can be built
      
      This moves the selection of the default .dts file out of the kernel
      config and into the bootwrapper makefile.  The makefile chooses which
      images to build based on the kernel config and the dts source file
      name is taken directly from the image name.  For example "cuImage.ebony"
      will use "ebony.dts" as the device tree source file.
      
      In addition, this patch allows a specific image to be requested from the
      command line by adding "cuImage.%" and "treeImage.%" targets to the list
      of valid built targets in arch/powerpc/Makefile.  This allows the default
      dts selection to be overridden.
      
      Another advantage to this change is it allows a single defconfig to be
      supplied for all boards using the same chip family and only differing in
      the device tree.
      
      Important note: This patch adds two new zImage targets; zImage.dtb.% and
      zImage.dtb.initrd.% for zImages with embedded dtb files.  Currently
      there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc,
      adder875-redboot and ep8248e.  This patch *changes the zImage filenames*
      for those platforms.  ie. 'zImage.ps3' is now 'zImage.dtb.ps3'.
      
      This new zImage.dtb targets were added so that the .dts file could be
      part of the dependancies list for building them.

      [POWERPC] Add -mno-spe for ARCH=powerpc builds · 0197cd2e
      Kumar Gala 提交于
      Newer GCC's are capable of autovectorization for ISA extensions like
      AltiVec and SPE.  If we happen to build with one of those compilers we
      will get SPE instructions in random kernel code.  Today we only allow
      basic interger code in the kernel and FP, AltiVec, or SPE in special
      explicit locations that have handled the proper saving and restoring of
      the register state (since on uniprocessor we lazy context switch the
      register state for FP, AltiVec, and SPE).
      
      -mno-spe disables the compiler for automatically generating SPE
      instructions without our knowledge.

      [POWERPC] Add Makefile rules to wrap dts file in zImage · 916066d5
      Mark A. Greer 提交于
      Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically
      compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file.
      The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and
      arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively.
      
      Having separate rules allows the user to choose whether to include a device
      tree--and which device tree--at build time.  This is useful when one Makefile
      target builds a zImage that runs on several platforms except for differing
      device trees.  By just setting CONFIG_DEVICE_TREE and running "make zImage.dts"
      the exact zImage you want is built without Makefile bloat or manually running
      the wrapper script.
      
      The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE)

      [POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot · 2bf11819
      Paul Mackerras 提交于
      This puts the knowledge of how to create various sorts of zImage
      wrappers into a script called "wrapper" that could be used outside of
      the kernel tree.  This changes arch/powerpc/boot so it first builds
      the files that the wrapper script needs, then runs it to create
      whatever flavours of zImage are required.
      
      This version does uImages as well.  The zImage names are changed
      slightly; zImage.pseries is the one with the PT_NOTE program header
      entry added, and zImage.pmac is the one without.  If the
      zImage.pseries gets made, it will also get hardlinked to zImage;
      otherwise, if zImage.pmac is made, it gets hardlinked to zImage.

      [PATCH] powerpc32: Set cpu explicitly in kernel compiles · f48b8296
      Olaf Hering 提交于
      Compile the 32bit kernel with -mcpu=powerpc. This reduces the imagesize
      when a compiler is used that defaults to -mtune=power4. It inserts lots
      of nops to please the 64bit cpu instruction scheduling. But all these nops
      are not needed for 32bit kernels.
      
      Example with SLES10 gcc 4.1.0 and arch/powerpc/configs/pmac32_defconfig:
      
                          vmlinux  vmlinux.strip  vmlinux.gz

      powerpc: Don't compile in arch/ppc/kernel for 32-bit ARCH=powerpc · e7e2d2da
      Paul Mackerras 提交于
      All of the things needed for 32-bit ARCH=powerpc builds have now
      moved to arch/powerpc/kernel, so we don't need to go down into
      arch/ppc/kernel any more, and we can remove the CONFIG_PPC_MERGE
      conditional from arch/ppc/kernel/Makefile.
      
      There were two files still referenced in the merge section of
      arch/ppc/kernel/Makefile: ppc-stub.o, depending on CONFIG_KGDB,
      and dma-mapping.o, depending on CONFIG_NOT_COHERENT_CACHE.  None
      of the platforms currently in ARCH=powerpc have caches that
      aren't coherent with DMA, but when we do get one we'll move
      dma-mapping.c over.  As for CONFIG_KGDB, none of the Kconfig
      files in the tree define it, so I'll let it languish for now.

      [PATCH] Fix building external modules on ppc32 · 70567293
      Andreas Gruenbacher 提交于
      We are setting up sources for building external modules like this:
      
        /usr/src/linux-obj> # create a .config file
        /usr/src/linux-obj> make -C /usr/src/linux O=$PWD oldconfig
        /usr/src/linux-obj> make -C /usr/src/linux O=$PWD prepare
        /usr/src/linux-obj> make -C /usr/src/linux O=$PWD scripts
        /usr/src/linux-obj> make -C /usr/src/linux O=$PWD clean
      
      After that, external modules can be built with:
      
        /usr/src/module> make -C /usr/src/linux-obj M=$PWD
      
      This fails for ppc32 because the `make clean' removes the
      arch/powerpc/include directory.  This should be done in archmrproper
      instead of in archclean.
