This is the initial import from Intel FSP release for Queensbay platform (Tunnel Creek processor and Topcliff Platform Controller Hub), which can be downloaded from Intel website. For more details, check http://www.intel.com/fsp. Note: U-Boot coding convention was applied to these codes, so it looks completely different from the original Intel release. Also update FSP support codes license header to use SPDX ID. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
