From a4ed3b653163367628d4ad173dfe3faf388da0ac Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 4 Mar 2012 22:56:52 -0500 Subject: [PATCH] sf: inline data constants I imagine much of these constants are due to copy & pasting previous drivers rather than an actual reflection of the hardware layout. At any rate, inline the info that we don't care about externally as it shrinks things nicely.
