Subject: [PATCH] board:samsung:trats/trats2: enable boot with appended and
separated DTB
This patch modifies envs to enable dual kernel boot
- with separated DTB if the DTB file is loaded successfully;
- with DTB apppended to uImage if DTB file is not found;
This is neccesssary for backward compatibilty.
