[yocto] The kernel *.cfg system

[Koehler, Yannick (HP Networking)]

Hi,

  I recently was playing with the FreeScale community layer meta-fsl-ppc.  They are using their own kernel package linux-qoriq-sdk.  I attempted to alter the configuration file using a systemd.cfg for the pleasure, to my surprise, the .cfg didn't change anything at all.  Is FreeScale playing Yocto rules properly or is it me that missed something ?  I did the same as with linux-yocto:

  FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
  KERNEL_FEATURES = "ext2 cgroups ipv6"
  SRC_URI += "file://systemd.cfg"

  Yet, the kernel .config didn't contained my changes like the linux-yocto did.  I was wondering if it was because the Qoriq Kernel didn't include specific Yocto recipe instructions or class and it was something that I could easily add or if this needed to come from FreeScale itself, or if it was really just my setup having a problem.  Note that I did copy the systemd.cfg file at a proper location and bitbake did find it, even thought the final config under the /tmp/work/... didn't contain the changes.

  Any help on this welcome.
