From 5ad03eb3854c162684222a718b44c0716ea0db03 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Thu, 31 Jan 2008 13:55:39 +0100 Subject: [new uImage] Factor out common image_get_ramdisk() routine Architecture specific do_bootm_linux() routines share common ramdisk image processing code. Move this code to a common helper routine.
