From 66a740572d7bcb18469e71cb014bfed3ff75a773 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 20 Oct 2006 15:30:55 +0900 Subject: [PATCH] sh: Convert INTC2 to IRQ table registration. Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way. This drops the ST40 tables, as nothing has been happening with those processors, while converting the only existing users to use the new table directly (SH7760 and SH7780).
