[POWERPC] Add flatdevtree source Add the latest version of the flatdevtree code and corresponding glue. A phandle table now tracks values returned by ft_find_device(). The value returned by ft_find_device() is a phandle which is really an index into the phandle table. The phandle table contains the address of the corresponding node. When the flat dt is edited/moved, the node pointers in the phandle table are updated accordingly so no phandles kept by the caller become stale. Signed-off-by: Mark A.

[POWERPC] bootwrapper: Add ft_root_node(). Clean up some of the open-coded data structure references by providing a function to return a pointer to the tree's root node. This is only used in high-level functions trying to access the root of the tree, not in low-level code that is actually manipulating the data structure.

[POWERPC] bootwrapper: Make ft_get_phandle() accept and return NULL. Currently, if ft_get_phandle() is passed NULL it will allocate an entry for it and return a non-NULL phandle.

[POWERPC] Add flatdevtree source Add the latest version of the flatdevtree code and corresponding glue. A phandle table now tracks values returned by ft_find_device(). The value returned by ft_find_device() is a phandle which is really an index into the phandle table. The phandle table contains the address of the corresponding node. When the flat dt is edited/moved, the node pointers in the phandle table are updated accordingly so no phandles kept by the caller become stale. Signed-off-by: Mark A.

[POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop() ft_set_prop() from flatdevtree.c in the zImage wrapper will either replace an existing property in the flat device tree, or add a new property definiion if the given property isn't present. However, when adding properties, it adds the property definition immediately before the node's END_NODE tag, potentially after any subnode definitions for the node. This confuses the kernel flat tree parser in prom.c which assumes that all property definitions for a node come before all subnode definitions. This patch corrects ft_set_prop() so that it adds new properties before the first subnode, instead of before the END_NODE tag.
