Do you have a load address?

Actually this comment is incorrect:
"Note: these instructions assume a 32-bit kernel. U-Boot does not currently
support booting a 64-bit kernel as it has no way of going into 64-bit mode on
x86."
U-Boot supports this. But you need to use x86_64 as the image type
instead of x86.
Are you booting with a 32- or 64-bit kernel?
Perhaps try without the 'qiuet'?
