From b0531b9b3299f3066b1db78f1693edabbba08b5c Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Sat, 3 Sep 2005 15:55:38 -0700 Subject: [PATCH] [PATCH] cpm_uart: Fix baseaddress for SMC 1 and 2 Base addess register for SMC 1 and 2 are never initialized. This means that they will not work unless a bootloader already configured them. The DPRAM already have space reserved, this patch just makes sure the base addess register is updated correctly on initialization.
