Hi all,

We have a FPGA which will be connected to the LPC bus. This FPGA will
provide some GPIO functionality, a rotary encoder, etc.

Now i want to write a kernel driver to talk to this FPGA.
I am unsure how to get access to the LPC bus in the first place.
What kernel APIs should i use? How to get the memory mapping right, etc?

I would appreciate any pointers to documentation or examples.


cheers,

Andre
