Hello Julien,

Hi Ihor,

Sorry for the late reply.

I suppose there is no such documentation, at least I didn't find any.
Bringing up XEN 4.10.0 on RK3399 is my pet-project.
My current target board is Ibox3399 <https://www.aliexpress.com/item/RK3399-Development-Board-Ibox3399-2GB-DDR3-16GB-EMMC-Six-Core-A72-A53-Mali-T860-GPU-Android6/32816273232.html>

At the moment I got dom0 running on this board and some test guest domain (both 4.4 kernels). Actually no changes made to XEN (except earlyprintk) at the moment, Xen works from the box.

Glad to see Xen booting out of box on RK3399 :).

The alias is only for convience. It would be possible to do the same with 8250,0xff1a0000,2.

So instead of that patch, I would suggest to write down a documentation for booting Xen on the board and early debugging.

What do you think?

        This patch enables earlyprintk for Rockchip rk3399 based SoC.

    Is there any missing pieces in Xen to boot on Rockchip? I would also
    quite like to see some documentation how to boot Xen on that platform.
