From 669f2d189e4c3a738ad2863a5f8f66a85d468bd9 Mon Sep 17 00:00:00 2001 From: Breno Lima Date: Tue, 20 Feb 2018 01:19:22 +0000 Subject: [PATCH] imx: hab: Keep CAAM clock enabled after authenticating additional images Currently it is not possible to run CMD_DEK on i.MX SPL targets: => dek_blob 0x12000000 0x12001000 128 The system hangs after running dek_blob because the CAAM clock is being disabled by the HAB code. There is no need to disable CAAM clock after authenticating additional boot images, thus keep CAAM clock enabled to address this issue.
