bootargs for dom0
The bootargs string for dom0 shall be provided as the xen,dom0-bootargs parameter in the /chosen node.
When preparing the device tree for dom0, Xen will set bootargs to the xen,dom0-bootargs value in the original device tree.
Example:
/ {
    [...]
    chosen {
        bootargs =  "console=serial0 dom0_mem=128M";
        xen,dom0-bootargs = "console=ttyAMA1 root=/dev/mmcblk0";
    }
    [...]
}
