[PATCH v2] [POWERPC] 85xx: Add next-level-cache property

Kumar Gala galak at kernel.crashing.org
Tue Jun 3 05:42:55 EST 2008 

Added next-level-cache to the L1 and a reference to the new L2 label.
This is per the ePAPR 0.94 spec.  Since we are't really dependent on this
today we aren't supporting the "legacy" l2-cache phandle that is specified
in the PPC v2.1 OF Binding spec.

---

Updated the commit message to be more explicit about rationale.

(in my powerpc.git powerpc-next branch)
