[yocto] Is it correct to specify uboot in MACHINE_FEATURES?

[Elvis Dowson]

Hi,
      For my overo-fire-chestnut43.conf machine configuration, if I specify u-boot in the EXTRA_IMAGEDEPENDS as follows:

EXTRA_IMAGEDEPENDS = "u-boot x-load"

Is there any purpose served by specifying uboot in the MACHINE_FEATURES as follows ?

MACHINE_FEATURES = "kernel26 alsa apm usbgadget usbhost vfat ext2 screen touchscreen serial ethernet uboot"

Best regards,
