From a4dc7ff08915a2035aa6d6decc53fa1deaa410bb Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 19 Sep 2006 14:06:27 +1000 Subject: [POWERPC] Define of_read_ulong helper There are various places where we want to extract an unsigned long value from a device-tree property that can be 1 or 2 cells in length. This replaces some open-coded calculations, and one place where we assumed without checking that properties were the length we wanted, with a little of_read_ulong() helper.
