This patch adds variables describing platform (soc, board, vendor)
to default environment and Samsung's common misc initialisation
to provide additional board information in envs.
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.
