Comparing a hex dump on the U-Boot command line with the contents of a file on the host system is fairly easy and convenient to do manually if it is small. But the format used hexdump by default differs from that shown by U-Boot. Add a note about how to make them the same.
(For large dumps, writing the data to the network with tftpput, or to a USB stick with ext4save is easiest.)
