Hi and welcome to the forum TRM! You've got some very nice builds on mediafire, very nice indeed! I don't have any advice to add to the excellent comments you have already received. As you have found out, there is a wealth of experience and knowledge on the site; and as important, the members are very happy to share it with others. I know I have learned a tremendous amount both about uboots in general and some pretty nifty techniques from the guys on here. I look forward to seeing your build whenever you decide to start and will be glad to answer any questions you might have.
