Linux Hang on io_block_mapping

Dear Greats

I am using MPC852T procesor with Linux version 2.4.26. I am in the
process of porting to this platform.

I am using Redboot and loaded the linux kernel. My system is having 32
MB (Micron 2 Chip solution) of RAM and 16 MB (Spansio) of flash.

My system is hanging during MMU_Init -> IO mapping of internal IMMR
register (0xFA200000). pte_alloc function for this mapping is failed.

Kindly guideme to solve this problem
