      Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc · 9fffb55f
      David Gibson authored
      
      The powerpc kernel always requires an Open Firmware like device tree
      to supply device information.  On systems without OF, this comes from
      a flattened device tree blob.  This blob is usually generated by dtc,
      a tool which compiles a text description of the device tree into the
      flattened format used by the kernel.  Sometimes, the bootwrapper makes
      small changes to the pre-compiled device tree blob (e.g. filling in
      the size of RAM).  To do this it uses the libfdt library.
      
      Because these are only used on powerpc, the code for both these tools
      is included under arch/powerpc/boot (these were imported and are
      periodically updated from the upstream dtc tree).
      
      However, the microblaze architecture, currently being prepared for
      merging to mainline also uses dtc to produce device tree blobs.  A few
      other archs have also mentioned some interest in using dtc.
      Therefore, this patch moves dtc and libfdt from arch/powerpc into
      scripts, where it can be used by any architecture.
      
      The vast bulk of this patch is a literal move, the rest is adjusting
      the various Makefiles to use dtc and libfdt correctly from their new
      locations.

      powerpc: Fix bug in kernel copy of libfdt's fdt_subnode_offset_namelen() · 2dccbf4e
      David Gibson authored
      
      There's currently an off-by-one bug in fdt_subnode_offset_namelen()
      which causes it to keep searching after it's finished the subnodes of
      the given parent, and into the subnodes of siblings of the original
      node which come after it in the tree.  This bug was introduced in
      commit ed95d745 ("powerpc: Update
      in-kernel dtc and libfdt to version 1.2.0").
      
      A patch has already been submitted to dtc/libfdt mainline.  We don't
      really want to pull in a new upstream version during the 2.6.28 cycle,
      but we should still fix this bug, hence this standalone version of the
      fix for the in-kernel libfdt.
