sorry for the delay.
Unfortunately this doesn't work. I've got a copy of my defconfig in
${WORKDIR} but as kernel_do_configure in meta/classes/kernel.bbclass contains:

        if [ -f "${WORKDIR}/defconfig" ] && [ ! -f "${B}/.config" ]; then
                cp "${WORKDIR}/defconfig" "${B}/.config"

and meta-fsl-ppc/recipes-kernel/linux/linux-qoriq-sdk.inc runs:

  do_configure_prepend() {

        cp ${KERNEL_DEFCONFIG} ${B}/.config

before kernel_do_configure, my ${WORKDIR}/defconfig is not copied into
{B}/.config.

Cheers,
Joerg
