From 9661b332041dab63ba2e5222b40a9f916c1368a9 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 6 Feb 2017 11:22:45 +0000 Subject: efi: Print the secure boot status in x86 setup_arch() Print the secure boot status in the x86 setup_arch() function, but otherwise do nothing more for now. More functionality will be added later, but this at least allows for testing.
