Contiguous Memory with Two 64MB SDRAM Chips on i.MX25

Hello,

 

My customer’s i.MX25 system has two 64MB SDRAM chips connected.  Since each chip select maps a 256MB region, the two SDRAMS are noncontiguous (a 192MB gap between them).  Can Linux be made to treat them as one 128MB RAM area or do we have to modify the ARM926’s MMU driver to remap them to a contiguous logical address space?
