As modifying the bootloader is out of the question, we can at least replace the environment it gives us with a more sensible one... In this talk, I'll give a brief introduction to what an EFI bootloader actually is, how they work, and how U-Boot fits into the picture as a second-stage bootloader. I'll cover the work I've been doing to improve Qualcomm support in upstream U-Boot, and how we can drastically lower the barrier of entry for distro support on Qualcomm phones. Lastly, I'll go over the new process for porting a Qualcomm SoC to U-Boot, and demo booting Linux with EFI runtime support on a Qualcomm phone. I'll also give a sneak peak at what would be possible if we had greater ownership of our devices. Why you should care This talk is primarily aimed at the upstream community, if you work on upstream support for any Qualcomm devices - be it phone, tablet, Chromebook, or vehicle - then you can likely benefit from running U-Boot. UEFI is now the lowest common denominator, and supporting it makes Qualcomm devices a viable target for more mainstream distros.
