From ebee0d4369b0f6f7ad082301a7d946f09e49bd25 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Tue, 26 Jun 2018 20:35:15 -0700 Subject: soc/intel/apollolake: Remove dead files Change a86d1b8 (soc/intel/common: Add SMM common code for Intel Platforms) moved APL to use common SMM code. However, smi.c and smm.h files under soc/intel/apollolake/ were not removed. This change removes the dead files since they are not used anymore.
