Please adopt in subject lines, commit logs, comments, etc. Similarly, "YAML" in comments & text, since acronyms are normally capitalized. "DesignWare" (not "Designware"). HiSilicon seems to use "HiKey" (not "Hikey"), so let's follow them. Pick either "Kirin 970" or "HiKey 970" From http://www.o.hisilicon.com/en/Products/ProductList/HiKey, it looks like "HiKey 970" refers to a board, and "Kirin 970" refers to a piece of it.
