From 6fb4efc68f5c0e095153510dcfa8b54a42e914ba Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Mon, 16 Oct 2006 13:50:05 -0700 Subject: [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.
