What is the reason for the reenaming? Especially, why changing from CONFIG_ to CONFIG_SYS_ ?
CONFIG_PBLRCW_CONFIG has 2 CONFIG. it is slightly confusing.
Reason for moving CONFIG_ to CONFIG_SYS: These defines enables of adding RCW(power on reset configuration) and PBI(pre boot loader commands) in u-boot image. These information will be used by SoC hardware for NAND, SD, SPI boot. As these configuration will be used by SoC hardware. I thought of adding CONFIG_SYS.
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,
