From 42a426e027df472714e8d6209cafac291935c331 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Wed, 6 May 2020 20:32:31 +0200 Subject: [PATCH] efi_loader: put device tree into EfiACPIReclaimMemory According to the UEFI spec ACPI tables should be placed in EfiACPIReclaimMemory. Let's do the same with the device tree.
