[PATCH v2 3/8] doc: Add a note about how to produce 'md' output using hexdump

[Simon Glass]

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.)

 For now: just type "help <command>".
 
+Note that the format of 'md' can be emulated from linux with:
