From 6bf05fd776e38a0a9c17e17c2345b59b1b9aa2cb Mon Sep 17 00:00:00 2001 From: Christian Krafft Date: Mon, 23 Apr 2007 21:35:45 +0200 Subject: [POWERPC] add of_iomap function The of_iomap function maps memory for a given device_node and returns a pointer to that memory. This is used at some places, so it makes sense to a seperate function.
