ARM SMP Linux not recognizing all cores on a RealView PB with ARM11MPCORE

Note: This was originally posted on 8th March 2010 at http://forums.arm.com
I have RealView Platform Base Board along with RealView Core Tile both having one ARM11MPCores on each.
Since each ARM11MPCore has 4 cores, there are 8 cores in total.
I am trying to bring up ARM SMP Linux on this using the instructions given at
[url="

"]
http://www.arm.com/community/software-enab...ux+OS+Downloads[/url]
I am able to run SMP Linux on this system using the binaries provided at this site.
However, if I enumerate the cpuinfo, I see only 4 cores. It does't show the cores belonging to the core tile cpu.
I also tried to build the SMP linux from source along with "CONFIG_NR_CPUS=8" configuration. But no success.
I can see all 8 cores in the scan chain using the Realview ICE JTAG.
I really appreciate any help to resolve this issue.
Thanks
