This is the first step in making it device-tree aware and get rid of the in-kernel EMC tables (of which there are none in mainline, thankfully). Changes since v3: * moved to devm_request_and_ioremap() in probe() Changes since v2: * D'oh -- missed a couple of variables that were added, never used and then later removed in a later patch. Changes since v1: * Fixed messed up indentation * Removed code that should be gone (was added here and removed later in series)
