From fd5f53f035ed7af472b3edfa0afaba9c9af667a0 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 26 Nov 2009 12:00:56 -0800 Subject: [PATCH] XScale: add stub {read,write}_phys routines Just make these fail, instead of letting them write over potentially random memory. Users should be able to work around the lack of real implementations by disbling the MMU by hand ... until someone provides a Real Fix.
