Linux boots on the iPhone 11, and we believe we’re the first in the world to do it.

Every line in the boot path is code we wrote. There is zero Apple code between power-on and Linux. The bootloader is ours, top to bottom. To our knowledge, no one has done this on an A13 device before.

Nice job, but are you Rosenzweig level? Because booting the kernel on iPhones has been done before. Getting a usable software stack is a whole other territory.
