From faa74b0fb81b3a1dd3e37f05774a24446057228a Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 31 Mar 2016 14:00:47 -0500 Subject: [PATCH] soc/intel/apollolake: use platform_segment_loaded() for CAR coherency Instead of using arch_segment_loaded() implement platform_segment_loaded() so as not to tangle the notion of arch and the chipset. Lastly, add a TODO to allow filtering of the L1D to L2 flush depending on the region loaded.
