From 2555e663b367b8d555e76023f4de3f6338c28d6c Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Wed, 1 Sep 2010 15:13:44 +0900 Subject: ARM: S5P64X0: Add UART serial support for S5P6450 This patch adds UART serial port support for S5P6450 SoC. The S5P6450 has 6 UARTs, so adds resource of UART4 and UART5. And to fix membase which is in serial/samsung.c is from Ben Dooks.
