2009-12-22	sh: kgdb: Rework breakpoint handling on top of notifier chain.	Paul Mundt	1	-1/+0
	This kills off kgdb's breakpoint handler and ties in to the notifier chain instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22	sh: Generic kgdb stub support.	Paul Mundt	1	-6/+7
	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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13	sh: Use a jump call table for debug trap handlers.	Paul Mundt	1	-0/+41
	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.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
