Played around with that. Look here: https://www.kraxel.org/cgit/jenkins/u-boot/tree/ https://www.kraxel.org/repos/jenkins/u-boot/ [ based on fedora uboot package, some vexpress patches on top ] Problems I ran into: * u-boot has no virto support. * sdcard emulation is painfully slow on arm kvm. Oh, and working with u-boot upstream is *ahem* a challenge. After trying to get a patch upstream (rpm patch #8) I'm not really surprised any more that there are so many u-boot forks around. Making edk2 fly on arm looks more promising to me. Especially for aarch64 of course, but also for armv7 + -M virt. cheers, Gerd
