From efaa6e266ba70439da00e7f1c8a218e243ae140a Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 24 Jul 2015 10:21:02 +0100 Subject: firmware: qcom_scm-32: replace open-coded call to __cpuc_flush_dcache_area() Rathe rthan directly accessing architecture internal functions, provide an "method"-centric wrapper for qcom_scm-32 to do what's necessary to ensure that the secure monitor can see the data. This is called "secure_flush_area" and ensures that the specified memory area is coherent across the secure boundary.
