Hi Peter,

HiKey is the first 96boards consumer edition compliant board. It features a hi6220 SoC which has eight ARM A53 cpu's.
This initial port adds support for: -
- Serial
- eMMC / sd card
- USB
- GPIO
It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.
Are there instructions somewhere on how to do this? Perhaps add a README with details or a few links?
Notes:
eMMC has been tested with basic reading of eMMC partition intto DDR. I have not tested writing / erasing. I suspect due to lack of clock control it won't be running in the most performant high speed mode.
SD card slot has been tested for reading and booting kernels into DDR. It is also currently used for saving the u-boot enviroment.
USB has been tested with ASIX networking adapter to tftpboot kernels into DDR. USB mass storage device enumeration doesn't currently work for an unkown reason.
GPIO has been tested using gpio toggle GPIO4_1-3 to flash LEDs.
Basic SoC datasheet can be found here: - https://github.com/96boards/documentation/blob/master/hikey/ Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf
Board schematic can be found here: - https://github.com/96boards/documentation/blob/master/hikey/ 96Boards-Hikey-Rev-A1.pdf

Can we use device tree for this board? I have just received one so if you don't have the time for this I could give it a try (once I figure out how to get U-Boot onto the board).
Also, do you know anything about the SDRAM controller? I don't see mention of it in the docs and we would need it to create an SPL for this board.
