From f413d0d9fa7abcecc40e115cf4aead372d164a75 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 13 Dec 2006 17:40:05 +0900 Subject: sh: Use a jump call table for debug trap handlers. This rips out most of the needlessly complicated sh_bios and kgdb trap handling, and forces it all through a common fast dispatch path. As more debug traps are inserted, it's important to keep them in sync for all of the parts, not just SH-3/4. As the SH-2 parts are unable to do traps in the >= 0x40 range, we restrict the debug traps to the 0x30-0x3f range on all parts, and also bump the kgdb breakpoint trap down in to this range (from 0xff to 0x3c) so it's possible to use for nommu. Optionally, this table can be padded out to catch spurious traps for SH-3/4, but we don't do that yet..
