It's been a while since I looked at u-boot-utils, I think the tools are
generic but the build scripts need a config to run.

I guess you mean "oe_runmake ${UBOOT_MACHINE}_config" :-)

I doubt I'm the only one who uses OE to generate Linux images without having a
suitable U-Boot machine that could be used to satisfy that. We could put
Sandpoint8240 in each such machine conf and document why there. I also assume
that there are machine confs that currently lack a UBOOT_MACHINE variable
which could cause problems building the U-Boot tools if this change is made,
especially for machines that might exist in an overlay (more likely now with
OE-core?).

I think they are generic, though I'm no expert.
