From 65e38e32a959dbbb0bf5cf1ae699789f81759be6 Mon Sep 17 00:00:00 2001 From: Nageswara R Sastry Date: Wed, 24 Nov 2021 12:38:01 +0530 Subject: selftests/kexec: Enable secureboot tests for PowerPC Existing test cases determine secureboot state using efi variable, which is available only on x86 architecture. Add support for determining secureboot state using device tree property on PowerNV architecture.
