uClinux on nios2 with Serial RAPID I/O

Hi all,

I have to configure uClinux to work together with Serial RAPID I/O. As far as I know to configure it for other architectures, such as powerpc, I have to enable the CONFIG_HAS_RAPIDIO in the Linux Kernel config file. Is it the same for nios2? Or better, how to introduce a Serial RAPID I/O uClinux device driver for nios2? Does anyone have experience on this?

Thanks in advance
