From 7d170b1bc540a1d83098a9f27cf4939e026fda81 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 8 May 2009 17:41:59 +0900 Subject: sh: Move out cayman-specific panic handler code to its own file. This moves out the cayman-specific panic handler code to a better location, and leaves the generic implementation a simple stub that is still used under emulation.
