From ab6e570ba33dbee18c2520d386e0f367a9b573c3 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 11 Dec 2008 18:46:46 +0900 Subject: sh: Generic kgdb stub support. This migrates from the old bitrotted kgdb stub implementation and moves to the generic stub. In the process support for SH-2/SH-2A is also added, which the old stub never provided.
