help
Enable this if building the u-boot.rom target needs binary blobs, and
so cannot be done normally. In this case, U-Boot will only build the
ROM if the required blobs exist. If not, you will see an warning like:

This option allows to build a ROM version of U-Boot.
The build process generally requires several binary blobs
which are not shipped in the U-Boot source tree.
