[U-Boot] [PATCH 0/6] Add support for hi6220 SoC and HiKey 96boards CE board.

[Peter Griffin]

This series adds support for the first 96boards consumer edition HiKey board.

More information can be found about this board at the following link
https://www.96boards.org/products/hikey/.

This initial port adds support for: -
1) Serial 
2) eMMC and sd card
3) USB
4) GPIO

It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.

Some (slightly old) instructions on exactly how to compile everything (l-loader, 
with Arm Trusted Firmware, which then loads u-boot are available here: -

http://people.linaro.org/~peter.griffin/hikey/hikey-u-boot-release_r1/u-boot-readme.txt.

One thing I'm fairly sure is wrong but can't see how to fix is the header definitions
are currently in arch/arm/include/asm/arch-armv8/*.h and I suspect they should
be in a directory something like arch/arm/include/asm/arch-hi6220. However so far what
makes this magic happen and how to fix it has aluded me.

Notes:

eMMC has been tested with basic reading of eMMC partition into 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 does not currently work for
an unknown reason (leads to a hang).

GPIO has been tested using gpio toggle command GPIO4_1-3 to flash LEDs.
