Subject: [MIPS] Only register RAM as resources if UNCAC_BASE != IO_BASE.
X-Git-Tag: v2.6.18-rc1~353^2~31
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6adb5fe7020e8f99d27da932157ea27325df9263;p=linux-2.6

[MIPS] Only register RAM as resources if UNCAC_BASE != IO_BASE.

This fixes a resource collision of RAM and I/O memory on systems that
use the physical address space multiple times.
