I'm committing some new stuff for the Iwill DK8S2 mainboard to replace the old stuff in src/mainboard/Iwill/DK8S2. I'm also adding a targets/Iwill/dk8s2 directory. Looks a lot like the HDAMA, but some tweaking is needed and VGA has not yet been tested, I'll look into it further today. So far I've tested it and it boots into Linux.
