Hi, Sorry for the late response. I just got a chance to test on a pinebook-pro, and was able to use a generated image on it. Screen wouldn't turn on but I got a functioning shell on serial; I was still just using mainline linux-libre-arm64-generic so I don't think that's a bootloader problem. > Here's an attached patch that should do that, but I'm not sure it brings > a real improvement, unless there are a lot of different offset out > there. I'm all for extensability, so that sounds good to me. Over the past few days I've been playing with u-boot, and I think that the install offset may be configurable, with the current offset just being used for compatability with Rockchip's proprietary miniloader. I could make a patchset to move u-boot up and test it out on the pinebook-pro and rockpro64, if that would be a better solution? Thanks!
