From 29ec6778a49d30c47345afdfaf1d03acff3cf656 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 15 Jan 2008 12:47:53 +0900 Subject: sh: remove voyagergx This patch removes redundant irq handling code together with unused consistent alloc code. R2D uart setup code is changed to use sm501-regs.h and unused header files are removed.
