I'm hesitant to take this file list as I think it highly depends on what you want to do with the board. For example at SUSE we use a ubootconfig.txt which get's added to config.txt. We might want to update grub, our kernel is on a different partition etc.
What do you think?
Other then that the patches look good, and I understand that they should go through my tree, also I don't know much about the FAT implementation.
