In have a sdram of size 9MB which i would map to kernel space (ioremap would do that ) the whole 9 MB kernel virtual memory i need to map to the application , the application would read when driver has complited writing and vice versa this implimentation would be in a circular buffer type. The size of my RAM is 128 MB
