[PATCH] powerpc: Update OF address parsers
This updates the OF address parsers to return the IO flags indicating the type of address obtained. It also adds a PCI call for converting physical addresses that hit IO space into into IO tokens, and add routines that return the translated addresses into struct resource Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
