From b86ce01c7700cfc74665799355a46dcadf920ebd Mon Sep 17 00:00:00 2001 From: Jean-Christophe DUBOIS Date: Fri, 20 Jul 2007 21:39:25 +0200 Subject: [PATCH] [CELL] allow linux to map Cell regs on legacy SLOF tree. The platforms missing the "cpus" property in the "be" node are mono-Cell platforms such as CAB or Getaway. Therefore it is possible to assume that if there is no "cpus" properties under the "be" node then we can safely return the "device node" without more checking. This is a bit hacky but ... it allows it to work on these platforms.
