CONFIG_ means stuff that can be freely adjusted by the end user to
match his likings, like adding one command and removing another.
CONFIG_SYS_ means stuff that is determined by the hardware
configuration, i. e. that has to be adjusted according to specific
properties to make U-Boot working on some hardware, and which can (or
should) not be "adjusted" by the end user.

I don;t understand your intentions enough to say which applies here;
IIRC at least PBI might be more of the CONFIG_ type.

Best regards,

Wolfgang Denk
