implementing mmap to access an FPGA connected an ARM9 processor running linux 2.6
I have a ARM9 processor running linux 2.6. It is connected to a FPGA and I want to access the FPGA memory using mmap(). Can I use the mmap() syscall or do I have to implement my own driver for this which implements mmap() syscall. I googled the internet and saw a few sample character drivers, they allocate a fresh memory from the kernel for the driver, but I need to map tp particular address in the physical memory (0xa0000000 - FPGA memory). How Do I do that??
