From d550414434f4250e80847382fac92f7e3891d887 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Thu, 11 Jan 2018 08:16:01 +0100 Subject: [PATCH] efi_loader: debug output installed device path When a device path protocol is installed write the device path to the console in debug mode. For printing the new macro EFI_PRINT is used, which can be reused for future diagnostic output.
