I've been wondering about the "u-boot-fw-utils-cross" recipe myself.
When I build the recipe I get what appear to be the correct binaries for
the host architecture, located in the target-specific work directory
(e.g. tmp/work/imx6qsabresd-poky-linux-gnueabi/u-boot-fw-utils-cross).
However, these binaries don't get installed anywhere other recipes (like
my sdcard image) would be able to find them.

My workaround so far has been to build a native package instead (by
simply adding BBCLASSEXTEND = "native" to the regular "u-boot-fw-utils"
recipe).
This way the binaries get installed to the host's sysroot and are found
just fine, but I feel like I'm missing something about how the cross
recipe should be used properly for this purpose.

Can anyone shed some light on this?
