From c13093b1484565382bd5e00722149442e46635ee Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Wed, 23 Sep 2009 18:51:03 +0000 Subject: simplify source tree hierarchy: move files from sdram/ and ram/ to lib/ It's only three files. Also fix up all the paths (Gotta love included C files) Signed-off-by: Stefan Reinauer Acked-by: Ronald G.
