Booting from SD card seems currently broken in their EDK2 firmware (as of 16.06): https://bugs.96boards.org/show_bug.cgi?id=177 Using the latest Linaro l-loader.bin and fip.bin files seems to resolve this.
With a Factory based EFI image you currently need earlycon to get serial output, with the Contrib:96boards hikey image earlycon=pl011,0xf7113000.
You also seem to need the following line:
As alternative to Tianocore with the above device tree limitations, you can try U-Boot as bootloader:
Connect a suitable Micro USB cable (e.g., to USB 2.0 Type A) between HiKey board and your host.
Install the jumper 3-4 (J601 on LeMaker HiKey) for recovery boot, then power on the board.
You will not see any serial output, but a new /dev/ttyUSBx device should appear.
This will boot into a special Arm Trusted Firmware mode where you can use the Android fastboot protocol over USB to flash new firmware:
Note: Files transferred via fastboot currently need to have 512-byte alignment (b9o#633). If you wish to flash your own files, make sure the files are aligned by adding suitable zero padding bytes at the end, as instructed in the bug comment #1.
Remember to remove the jumper 3-4 before you do
fastboot reboot or a reset.
You will then need to install on your HiKey boot medium the dtb-hisilicon package matching your kernel, and our U-Boot should pick it up automatically.
JeOS-efi (and modified JeOS-hikey) gets stuck during early boot: Bug #1040492
If you broke your board due to broken sotfware, you can follow upstream recovery manual: https://www.96boards.org/documentation/consumer/hikey/hikey620/installation/board-recovery.md.html
