From 13d06981a9829c9edcfd6f9f582d216fbaed95e5 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 8 May 2013 08:06:01 +0000 Subject: image: Add device tree setup to image library This seems to be a common function for several architectures, so create a common function rather than duplicating the code in each arch. Also make an attempt to avoid introducing #ifdefs in the new code, partly by removing useless #ifdefs around function declarations in the image.h header.
