Thread-topic: 1 GB RAM with RM9000 SOC
Hi list,


Any of you successfully used >512MB ram with MIPS SOC's.  I have a
requirement where I have to use 1 GB ram with RM9000 based SOC. 

I have enabled 64 Bit support and so far it is working with 512 MB of
RAM. How ever if I increase memory beyond 512MB I am getting kernel


 I am adding memory region from 0x00 add_memory_region(0 ,0x40000000 ,
BOOT_MEM_RAM). (PMON maps RAM from 0x0 to 0x40000000)  Am I wrong here?


It will be great if you can give some suggestion /point me to a working
implementation. I am using 2.6.18 kernel.
