No, this is wrong. CONFIG_... is supposed  to  be  user  configurable
options  (i.  e.  things  you  can  easily change in a specific board
configuration to adjust U-Boot  to  your  needs  or  likings),  while
CFG_... are specifcic configurations necessary to make U-Boot work on
a specific hardware, i. e. they cannot be changed unless the hardware
changes, to (in general, at least).

Best regards,
