And some other differences: 1. *fruit* devices use an ARM64 which is already documented anyway. 2. *fruit* devices are more "popular" and the maintainer can test on it more easily. And *fruit* have more fans (esp. more fans with CS/EE skills, while we have more [expletive deleted] fans :( ) so their reverse-engineer effort is easier as well. Yes it may be not fair to others, but the world is just not fair. 3. *fruit* is really a bad example... When people ask me how to build Linux From Scratch on *fruit* I just tell them "try to avoid things from a vendor with no intention to allow you run another OS". -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
