Porting and maintaining Linux for a Multimedia SoC is one thing (already very complex), but without a proper Bootloader, how would we do ? For the last 4 Years, we were pushing Upstream Linux support for the Amlogic Multimedia SoCs with very well-known Single Board Computers like Odroid-C2, Libre Computer Le Potato, Khadas VIMs... but a key point was missing until 2 years ago: a clean Bootloader. We only relied on the Vendor Bootloader, but it quickly became an issue for various reasons: - was complex to rebuild - even more complex to enhance and fix - did some weird and quirkly hardware enablement before linux - was confusing because the vendor Bootloader behavior changed over time So we implemented an all-most complete U-Boot support for these Amlogic SoCs, including HDMI video support and support Android AOSP boot. And a big bonus appeared: we got UEFI support for free ! Neil will go through all the development process, what we achieved, the remaining work and how U-Boot maintenance and code quality evolved over time.
