From 8a3588a7c8d15d53aeaa0080f47e1f949390ab71 Mon Sep 17 00:00:00 2001 From: Sughosh Ganu Date: Wed, 14 Nov 2018 10:40:33 +0530 Subject: [PATCH] SPM: EHF: Build EHF module along with Secure Partition Manager Add a dependency for building EL3 exception handling framework(EHF) module with the secure partition manager(SPM). The EHF module is needed for raising the core's running priority before the core enters the secure partition, and lowering it subsequently on exit from the secure partition.
