I am trying to boot a reasonable qemu instance that was running for about a dozen hours. I have four qemu raw disk images which have valid GPT partition labels and filesystem regions therein thus :

However u-boot blows up with a complaint about the filesystem type ??

Is there an update to u-boot that recognizes the valid GPT partition labels ?
