Hi
I am working with an Arm. It has several Chip Select Lines. I am working on a kernel module, using RTAI.
From User Space I can use open("/dev/mem", O_RDWR | O_SYNC) and mmap to access the memory for the CS Lines.
How can I do that in kernel Space?
Thank Frank benoit at tionex de
Ok, in comp.os.linux.development.system

I found the answer:
ptr = ioremap( physaddr, length );
