What is the best way to configure a layer to support multiple targets that
share a common base?
For example, a set of targets that use the Vortex86DX SOC share common
peripherals and also have per-variant peripherals.
I was thinking:
1) Have a conf/machine file for each variant;
2) Make these use an include for the Vortex86DX SOC.
However, I can't work out how to get a per-machine defconfig file. Is there
some way of using the machine name to do this? Can I just use
FILESEXTRAPATHS := "${THISDIR}/${PN}/${MACHINE}"
in a kernel .bbappend file?
That shouldn't even be necessary. Just something like this:
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}"
and it will look for files in various directories
${THISDIR}/${PN}/${MACHINE}
${THISDIR}/${PN}
(and maybe some others)
For example, I have one layer for a project which supports
three different targets (all part of the same platform) using
this technique.
