Commit 430b01e8f5e524a2bfa50074d97d0bdc2505807b ("[POWERPC] Kill flatdevtree.c") killed the two files including flatdevtree_env.h. It was apparently just an oversight to not kill that header too. Kill it now. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
