From 6235df946ed391dc2ca5e5a9e8f05c02d7c2d3be Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Mon, 28 Mar 2011 18:33:57 +0200 Subject: MIPS: IncaIP: Move all IncaIP specific code to separate subdirectory IncaIP is a SoC and its specific code should reside in an own SoC subdirectory. Also add -mtune=4kc flag for CPU optimization.
