new way
With the opensource ATF we switched to full 64bit mode,fip (bl31+uboot) and fit kernel

only uboot-mtk.bin (with littlekernel=LK) works
A better ATF is mt7622_atf_push_wps_uboot_64.img (can be found on my gdrive too) supports booting 32bit uboot by default and 64bit uboot by pressing wps-button

This can also be done in recent uboot

mmc partconf 0 1 1 0
after this steps preloader gets loaded (i had only flashed preloader here and nothing alse, so error is correct…full boot needs additional headers HEAD0,HEAD1,SD-Preloader,ATF and UBOOT)…

boot from emmc till uboot:
http://forum.banana-pi.org/t/bpi-r64-quick-start-boot-from-emmc/9809/36
i've created a small script with all headers needed for emmc-boot: https://drive.google.com/open?id=1a8yCzwiCAcqtHHXDLhRzMdItsMC7ndJr 
this erases content of emmc! if you do not want this, comment out lines for writing partition table and formatting
