From c014d164f21dbdbe721a4ec7e5147591c4eed545 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Thu, 9 Jul 2015 10:40:43 +0100 Subject: MIPS: Add platform callback before initializing the L2 cache Allow platforms to perform platform-specific steps before configuring the L2 cache. This is necessary for platforms with CM3 since the L2 parameters no longer live in the Config2 register.
