From 2a58364da0c04f8dc42cdfe7a4de9d17e536cda8 Mon Sep 17 00:00:00 2001 From: Tomoya MORINAGA Date: Mon, 26 Mar 2012 14:43:01 +0900 Subject: [PATCH] pch_uart: change type to u8 Target uart register access size is 8bit. However, 32bit is used at 2 points. This patch modifies type "unsigned int" to "unsigned char".
