From dea2174d9d941db2ec64997779771a4b4c3527c2 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 4 Mar 2016 01:10:13 +0100 Subject: [PATCH] efi_loader: Call fdt preparation functions We have a nice framework around image fils to prepare a device tree for OS execution. That one patches in missing device tree nodes and fixes up the memory range bits. We need to call that one from the EFI boot path too to get all those nice fixups. This patch adds the call.
