Scaleway - XEN support

0_README.md

I'm trying to boot xen on Scaleway C1

I don't have any output on console after u-boot jumps on xen

The hardware console is ttyS0,9600n8

I'm using a xen image found in ubuntu's xen-hypervisor-4.5-armhf package (/boot/xen-4.5-armhf) converted to uImage using mkimage

---

Questions:

• What is the mapping between bootargs, xen,xen-bootargs, xen,dom0-bootargs and xen, host kernel ?
• Which console should be set ? where ?

Attached, you will find

• .dts file
• u-boot commands
