Start split out of common open firmware code
This creates drivers/of/base.c (depending on CONFIG_OF) and puts the first trivially common bits from the prom.c files into it. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Paul Mackerras <paulus@samba.org> Acked-by: David S. Miller <davem@davemloft.net>
