Thanks for reviewing the patches.

The fit image support is nice as it is the u-boot default boot image for 
zynq. This is not major blocker, user can always manually loads the kernel.

If the SPL loading the bitstream is the main reason hold off u-boot 
patches, i can break that patch into two patches. let me know what's you 
want me to do.

Best regards,

Jason
