From 85835f442e5bbf9d3b8f6e574751da8db77016d2 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sun, 30 Apr 2006 11:15:58 +0100 Subject: [PATCH] [SERIAL] AMD Alchemy UART: claim memory range I've noticed that the 8250/Au1x00 driver (drivers/serial/8250_au1x00.c) doesn't claim UART memory ranges and uses wrong (KSEG1-based) UART addresses instead of the physical ones.
