From bcc3c49c90a1e79befa72b8871d4d4c6031c15b7 Mon Sep 17 00:00:00 2001 From: Soby Mathew Date: Mon, 10 Apr 2017 22:35:42 +0100 Subject: PSCI: Build option to enable D-Caches early in warmboot This patch introduces a build option to enable D-cache early on the CPU after warm boot. This is applicable for platforms which do not require interconnect programming to enable cache coherency (eg: single cluster platforms). If this option is enabled, then warm boot path enables D-caches immediately after enabling MMU.
