-gerrit commit d1d7a8ef71e0618c6e0553c8868bb2b88e7a9be5 Author: Ronald G. Minnich <[email protected]> Date: Fri Mar 8 15:24:44 2013 -0800 samsung/exynos5: add resource functions for the display port Not working, seemingly, but we need to add a 4M resource for memory, and it seems it needs to be fixed at the address shown. This address chosen from current hardware. Change-Id: Ied65a554f833566be817540702f79a02e7b6cb6e Signed-off-by: Ronald G.
