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
