This code is from U-Boot. Please say so in the commit message, possibly
also which commit you used. Also for the other patches. Wolfgang once
complained about not doing so for code we used from U-Boot.

The function name is a poor choice as it doesn't give a clue about its
return value. Does it return 'Yes, the check failed" or "Yes, the check
is ok"?. Please rename to something like ddr2_spd_checksum_ok.
