From 2db1eba1c3717856ebcf01727379ad2d3f19b3cc Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Tue, 3 Apr 2018 22:40:55 +0200 Subject: [PATCH] efi_loader: correctly determine the boot partition The device path of the loaded image should be set to the partition from which the image was loaded. This requires using the same logic as the load command. Without the patch the device path pointed to the whole disk after executing load mmc 0: 0x43000000 FILE and not to the boot partition from which the file was actually loaded.
