for barebox point of view just be able to change the projects name will be enough as most
of us if not all are kernel dev or maintainer

ok take a look on arch/arm/mach-at91/Kconfig

as example for the

config BOARDINFO
        default "Atmel at91rm9200-ek" if MACH_AT91RM9200EK
        default "Atmel 91SAM9260-EK" if MACH_AT91SAM9260EK
        default "Atmel at91sam9261-ek" if MACH_AT91SAM9261EK
        default "Atmel at91sam9263-ek" if MACH_AT91SAM9263EK
        default "Bucyrus MMC-CPU" if MACH_MMCCPU
        default "Ronetix PM9261" if MACH_PM9261
        default "Ronetix PM9263" if MACH_PM9263

if you change the board via the interface it will not be change and it will the same for
config ARCH_TEXT_BASE in some case

and I'll prefer to do set BOARDINFO="Atmel at91rm9200-ek" from the config MACH_AT91RM9200EK

hope it will be a good example
