I did get past this, after I updated the SRCREV_meta with the correct commit,
which resulted in the correct kconfig fragment being picked up, with enabled
the device tree option in the kernel.

However, I'm unable to get qemu to boot correctly, for both ARM Cortex A9
and ARM Cortex A* (beagle). Maybe this has to do with the fact that it needs
xload+uboot in addition to the kernel, using an SD card image.

Any suggestions on how I can do this?

I'd like to know how qemuarmv6, qemuarmv9 and qemuarma9 were tested
earlier.

I think its important to get atleast the A8 and A( QEMU platforms up and running
in oe-core, since they represent a bunch of the current targets used for actual
development.

Best regards,
