[ORLinux] How to write a driver for GPIO and load it in kernel

[karthik gunda]

Hi all,

I have my module gpio which is located at address "0x91000000" in the
ORPSOC that i am working . After booting linux on FPGA (i.e) when Linux is
Running I want to run a C program that blinks the leds on My FPGA. I have
assigned the constraints in UCF file for GPIO.

So please help me in doing this job

Thanks,
Karthik.
