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 <stepan@coresystems.de> Acked-by: Ronald G. Minnich <rminnich@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4661 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
