[PATCH v2 0/8] efi_loader: improve device-tree loading

[Heinrich Schuchardt]

In U-Boot EFI boot options can already specify both an EFI binary and
an initrd. With this series we can additionally define the matching
device-tree to be loaded in the boot option.

With the last patch the boot manager will fall back the device-tree
specified by $fdtfile in directories '/dtb/', '/', or '/dtb/current/'
on the boot device if no device-tree is specified in the boot
option or via a bootefi command parameter.

v2:
	Update efi_dp_concat() instead of new function efi_dp_merge().
	Carve out a function efi_load_option_dp_join() which we can
	use both for the eficonfig and the efidebug command.
	Rename variables id_dp, final_dp_size.
	Rename create_initrd_dp() to create_lo_dp_part().
	Use enum as parameter for create_lo_dp_part().
	Put all related changes into one patch.
