Hello Kumar

Could you please accept this patch if it is okay.

> 
> P1020 is another member of Freescale QorIQ series of processors.
> It is an e500 based dual core SOC.
> Being a scaled down version of P2020 it has following 
> differences from P2020:
> - 533MHz - 800MHz core frequency.
> - 256Kbyte L2 cache
> - Ethernet controllers with classification capabilities(new 
> controller).
> From board perspective P1020RDB is same as P2020RDB.
> 
> * This code adds the basic basic platform support for P1020RDB.

> - based on 
> http://www.kernel.org/pub/scm/linux/kernel/git/galak/powerpc.git
> - branch->next
> - The patch does not contain ethernet support because P1020 
> contains new eTSEC
>   controller. The support will be added in the later patches.
