From 3400655e0f3cb6a8ca2b486137e96f576c9cd2fc Mon Sep 17 00:00:00 2001 From: Vasili Galka Date: Tue, 26 Aug 2014 14:05:31 +0300 Subject: mpc5xxx: Add stub implementation of cache functions Some drivers (e.g. net/e1000) reference these functions. So, this fixes the build of MVBC_P board. I'm not familiar with the MPC5xxx platform, maybe a full implementation shall be implemented instead of this stub in the future.
