Hi,

I got tired of switching out the jumper, connecting the micro-USB cable, etc and tried:

    root@hikey:~# dd if=/tmp/fip.bin of=/dev/mmcblk0p4

Which works, so if you want to upgrade UEFI you can do it in linux. And with the latest changes by Leo that I just merged into ATF 'reboot' now works as well!

I think this method will still leave BL1 part of ATF at the previous version. The dd command will upgrade BL2-BL3 of trusted firmware along with UEFI build.
