From 751c9f684963d2a066a79d8022c0e79e1159291b Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 22 Nov 2011 14:46:49 +0000 Subject: MIPS: Oceton: Update model detection code for new chips. Several newer chips were not covered, update the code to detect them. This necessitates updating cvmx-mio-defs.h as well, because it has new and required definitions.
