This is a Yocto meta layer for buiding fwup into Yocto projects.
It is really close, but not quite right yet. Since I'm not a Yocto user myself,
I'm not actively working on this. However, it seems close enough to provide a
head start to anyone using Yocto that it's worth sharing.
For conf/bblayers.conf you have to add
BBLAYERS ?= " \
...
path_to_source/sources/meta-fwup \
"
Or add IMAGE_INSTALL_append = " fwup" in conf/local.conf and run
bitbake core-image-minimal to get an image with fwup support.
