Please make this optional.  I don't want the increased code size for
all boards when probablyonly one or two will ever activate this.  And
please add documentation, and include a note that the use of this
option is discouraged, as the problem should be addressed outside
U-Boot.

Best regards,

Wolfgang Denk
