PATCH 1/1 board/pcengines/apu2: add config
The apu2 by PC Engines is a 64 bit single board computer with coreboot BIOS. It only has serial output, but no graphics chip. With its 2?4 ethernet ports, it is often used to build a firewall or router.
The provided defconfig configures busybox and isolinux. It will output a hybrid ISO image that can be written to a USB stick or burned to a CD.

Sorry for the long delay. I've applied to our master branch, with just a fix to the commit title and the indentation of the DEVELOPERS file. Of course, if you want to send a further update to upgrade the kernel to a newer version, that would be nice. Another nice improvement would be to select a more specific CPU than just "x86-64", i.e you could select the specific x86-64 CPU that the APU2 is using.
Thanks!

PATCH 1/1 board/pcengines/apu2: add config
Hello Thomas
Thank you for the merge!
At the moment the APU2 I used for developing this defconfig is in active use, so I cannot test an updated config. However, I may be able to update the config by the end of the year (no promises though!).
