From 856b284617eea5688ccf5f4655f8d70ac5ae5fbb Mon Sep 17 00:00:00 2001 From: Aneesh Bansal Date: Fri, 22 Jan 2016 16:37:28 +0530 Subject: [PATCH] secure_boot: change error handler for esbc_validate In case of error while executing esbc_validate command, SNVS transition and issue of reset is required only for secure-boot. If boot mode is non-secure, this is not required. Similarly, esbc_halt command which puts the core in Spin Loop is applicable only for Secure Boot.
