Actually, this patch is a RESEND of my v2[1], without patch #2 and #3 as I don't want to dive into details of dtb discussions[2]. I think that the patch #1 alone is useful.
If fdt_addr_r is not defined, "load ... ${fdt_addr_r} ${prefix}${efi_fdtfile}" will fail quietly. So it should be OK.
Think about applying my "removable device" patch[3] alongside this patch.

Changes in v3 (Nov 27, 2018): * remove v2's patch #2 and #3
Changes in v2 (Oct 22, 2018): * rewrite my previous changes after Alex's comments, including - boot bootmgr only once before searching for boot binary - dtb must be loaded from the same device with boot binary's * add patch#2 as part of this patch set, in particular adding CONFIG_SYS
Thanks, -Takahio Akashi
