[meta-freescale] linux-boundary bbappend misses .cfg

[Sébastien Taylor]

I am trying to enable cgroups using a configuration fragment following the guidelines in the development manual section 5.6.2.  I see my cgroups.cfg file is copied to the linux-boundary/3.0.35-r0/cgroups.cfg but otherwise it doesn't make it's way into the kernel configuration.

The setup uses meta-mylayer/recipes-kernel/linux/linux-boundary_3.0.35.bbappend with the contents

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI_append += "file://cgroups.cfg"

Then I have meta-mylayer/recipes-kernel/linux/files/cgroups.cfg

Like I said the cgroups.cfg is copied but never applied to the kernel configuration, the documentation claims that a .cfg file should automatically be appended to the kernel configuration but I guess there's an additional step that I've missed along the way.  Defining an alternate defconfig instead of a .cfg fragment does work as expected.
