In theory U-Boot built for coreboot is supposed to run as a payload to be loaded by coreboot on every board that coreboot supports. The U-Boot build process uses SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE which are hardcoded in board defconfig and Kconfig files. For better support of coreboot, we want to make these two options configurable so that we can easily change them during 'make menuconfig' so that the generated U-Boot image for coreboot is board configuration aware.
