Hi Dirk,

Could you share the U-Boot commands how you load and esp. start Xen? For
loading you use TFTP? How do you start Xen with U-Boot, then? I think we
have to pass the device tree address in x0 and the Linux kernel image
address in x2. How do you do this with an U-Boot command?
U-boot can load Xen from TFTP or from the SD-card. This is the same as
booting a baremetal kernel with U-boot.
There is a section on the wiki page to explain how to create the
device-tree node for the boot modules [1] and the allwinner page [2]
gives a full example how to boot Xen with U-boot via tftp (Note that it
could easily be adapted to load from the SD-Card).

Hmm, sorry, I still seem to miss anything :(
I've loaded xen/xen with U-Boot to 0x4A000000 and then try to start it
as described in [2] above:
=> bootz 0x4A000000 - 0x48000000
Bad Linux ARM zImage magic!
I'm not sure why xen/xen is assumed to be a zImage?
Oh, sorry I meant to say that bootz should be replaced by booti but
forgot to write it down.
