[PATCH] sh: sh2a MTU2 platform data

Magnus Damm
2009-04-30T07:06:26Z

From: Magnus Damm <damm@igel.co.jp>

This patch adds MTU2 platform data for the following cpus:
- sh7201 (3/5 channels)
- sh7203/sh7263 (2/4 channels)
- sh7206 (3/5 channels)
- MXG (3/5 channels)

Signed-off-by: Magnus Damm <damm@igel.co.jp>
