Re: [Linaro-uefi] [PATCH edk2-platforms v1 15/16] Hisilicon/D06: Use CalculateCrc16 in BaseLib

This patch is relative with "Add new API CalculateCrc16()" in edk2.

The commit message should describe what the patch does. I don't mind keeping the above line in, but we also need the description.

Obviously, this patch depends on the corresponding one going into edk2, which is has not yet.
