I need to add config_mpc85xx.h here.

   #define CONFIG_MPC85xx
   #define CONFIG_FSL_IFC                 /* Enable IFC Support */
   #define CONFIG_SYS_HAS_SERDES          /* common SERDES init code */
+#include "../../arch/powerpc/include/asm/config_mpc85xx.h"

I tried just after CONFIG_P1010 but it is giving compilation error.

Just to mention, I need to provide relative path in order to compile.
I will still suggest to keep original patch, As header file location may 
change over period of time then config file needs to be updated again.
