Hmm...  The same text appears in drivers/mtd/nand/nand_util.c, which  
does have a pre-existing v2-only header.  I probably applied it to  
cmd_nand.c as well because it was unclear whether the existing code was  
also v2-only.

The project-wide COPYING did not have the "or later" language until Jan  
9 2011 (commit b9347188729992ef8282a2854889d8dcc25175aa), so it's not  
clear to me that the project-wide license was GPLv2+ at the time that  
the older cmd_nand.c code was submitted, or even at the time that I  
added the above text.
