  "message": "[POWERPC] Cleanup zImage handling of kernel entry with flat device tree\n\nThis makes 2 changes to clean up the flat device tree handling\nlogic in the zImage wrapper.\n\nFirst, there were two callbacks from the dt_ops structure used for\nproducing a final flat tree to pass to the kerne: dt_ops.ft_pack()\nwhich packed the flat tree (possibly a no-op) and dt_ops.ft_addr()\nwhich retreived the address of the final blob.  Since they were only\never called together, this patch combines the two into a single new\ncallback, dt_ops.finalize().  This new callback does whatever\nplatform-dependent things are necessary to produce a final flat device\ntree blob, and returns the blob\u0027s addres.\n\nSecond, the current logic calls the kernel with a flat device tree if\none is build into the zImage wrapper, otherwise it boots the kernel\nwith a PROM pointer, expecting the kernel to copy the OF device tree\nitself.  This approach precludes the possibility of the platform\nwrapper code building a flat device tree from whatever\nplatform-specific information firmware provides.  Thus, this patch\ntakes the more sensible approach of invoking the kernel with a flat\ntree if the dt_ops.finalize callback provides one (by whatever means).\n\nSo, the dt_ops.finalize callback can be NULL, or can be a function\nwhich returns NULL.  In either case, the zImage wrapper logic assumes\nthat this is a platform with OF and invokes the kernel accordingly.\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
