Hello All

I have problem on the step of booting with xen with the reference site(http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Lager).

I have used the environment like below.

- xen version : xen4.6 Release version

- linux kernel : mainline 3.19.8 with DTS(r8a7790-lager.dts)

- Without using XSM module ( I got error message for compiling XSM module on ubuntu14.04 host, if any got how to compile let me know)

I had tried Âto setup board and started,and then got below message that did not bring up CPU1 ~ 7.

Lager board got brought up CPU0 only. Also did not get problem for the console.
