Agree, this does not scale at all. Anyway, I am asking which is the way
to do. A .bbappend works fine if the .bbappend file is put in a separate
layer - I did several times, and there are a lot of examples in
meta-<manufacturer name>.
But if the file is still in meta-eldk, it will be always included. So
one way could be to add a new layer with recipes-bsp and recipes-kernel,
and putting there the .bbappend files.
To add it to the same layer, I have not found any other way as to use an
include file for all general rules. So adding a u-boot-mkimage-mx28.bb,
that sets the SRC_URI and that includes u-boot-mkimage_2013.07.bb (maybe
changing the name..), and then setting a PREFERRED_PROVIDER into the
machin configuration file. But really I prefer the first solution adding
a layer for the hardware. I am curious if someone has found another
solution.
Best regards,
Stefano Babic
