From 9e144351e5ee0ce751a3d6c44e548a8b2e2cd2ac Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 13 Jun 2013 20:10:47 +0000 Subject: [PATCH] MIPS/OCTEON: Override default address space layout. OCTEON II cannot execute code in the default CAC_BASE space, so we supply a value (0x8000000000000000) that does work.
