From fb91e2cb7d3d44356bb92411d6d6b7cb51ce156c Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Wed, 12 Nov 2008 00:16:04 +0100 Subject: [PATCH] MIPS: RC32434: Define io_map_base for PCI controller The code is rather based on trial-and-error than knowledge. Verified Via Rhine functionality in PIO as well as MMIO mode.
