Hi Robert,

  currently, u-boot is being configured and compiled standalone -- not
as part of OE. and that build works just fine, so i can grab whatever
(little?) i need from that build to then add to an actual OE build so
i can just add u-boot-fw-utils to an existing image.

  as i read it, for an OE build of u-boot, i need to supply either
UBOOT_MACHINE or UBOOT_CONFIG. so in this case, what would i do? my
assumption until now is that i need to add to the OE build just enough
to get the fw utils to build, and i'd do that by setting either of
those variables. and i already have the appropriate fw_env.config file
ready to go.

  so what precisely do i need to do here?

Have you tried to override UBOOT_CONFIG in a u-boot-fw-utils bbappend?

Have a look at how we do that (using sandbox_defconfig) in meta-digi-arm:

Hope this helps.
