On OpenEmbedded-based systems, as is the case of Yocto Project, we
introduced the UBOOT_CONFIG mechanism for this. So for example in:

https://github.com/Freescale/meta-fsl-arm/blob/master/conf/machine/imx6slevk.conf#L15

The UBOOT_CONFIG is changed, in local.conf for a machine, to:

UBOOT_CONFIG = "spinor sd"

Both as build.
