[Xen-users] [xen-4.6-ARM][Renesas-Lager Board] Fail to enter rootfs on DOM0 after setting XEN



Hello,Â

After setting xen, DOM0 stop before find rootfs. In case of without-xen, rootfs Âwas found. But In case of with-xen, DOM0 was hold with bootargs like below.

xen,dom0-bootargs = "console=hvc0 earlyprintk=xen debug ignore_loglevel vmalloc=384M video=HDMI-A-1:1920x1080-32@60 ip=192.168.0.91:192.168.0.228:192.168.0.1:255.255.255.0:lager:eth0::: root=/dev/nfs rw nfsroot=192.168.0.228:/nfsroot/lager, nfsvers=3 rootdelay clk_ignore_unused";
