Hello, I am using MIPs-IDT79S334A. just now i noted that there is no ioremap.c file in source tree. this made me to think if physical memory that is normally ioremapped is already a part of processor memory map after startup hence no need to call it explicitly in drivers . Am i thinking right ..? pls let me know . Best Regards, Atul __________________________________________________________ Give your Company an email address like ravi @ ravi-exports.com.
