Formal complaint:  ifh you introduce new CONFIG_ options, you MUST
document these in the README.


What is worse is that your commit changes global behaviour of U-Boot
for all architectures, nearly all boards.

Even if you guess that some feature might not be used we cannot simply
remove it lightly.

If you want to make this configurable, then as an opt-out, but not
mandatory for everybody.



Best regards,

Wolfgang Denk
