Trying to netboot openbsd with u-boot
I've created a menu system using u-boot on the beaglebone black.
So far I was able to script loading the openbsd kernel over the network and execute it.
u-boot has a "bootargs" variable which is transfered to the kernel.
It's evidently the way of setting "boot device" and "root device". But I can't find the appropriate documentation nor can I deduce it. I can specify booting from disk and that works. But I want to mount root over nfs.
With bootargs not set it asks me for a boot device.
I want to pass to the kernel that it should mount root over a nfs serverip and path I specify such as 192.168.1.2:/nfs/beaglebone/openbsd
