Ok, I attach log files that are when boot each with initramfa and NFS
 file system based on linux mainline linux4.3.
1) With Xen4.6.1
a) renesas_with_xen4.6.1_NFS_linux4.3  - using  NFS file system with
tty node "ttySC0"
b) renesas_with_xen4.6.1_initramfs_linux4.3 - using initramfs

2) Without Xen4.6.1
a) renesas_with_native_NFS_linux4.3 - using  NFS file system with tty
node "hvc0"
b) renesas_with_xen4.6.1_initramfs_linux4.3 - using initramfs

I got the shell on native with both file system(nfs and initramfs),
but target board had hang during dom0 booting based on XEN.

I added only dts file need to xen according to
"http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Lager";.
That is all I did.

I attached initramfs file. this file is normal working on native linux system.
