Hi all,

I have been using the or1ksim for some time now and it works great.Now, I'm trying to make a linux driver for a SystemC interface that I added to the OPENRISC.

The problem comes when I try to make the driver I get the following error:
ERROR: "__ioremap" [arch/or32/drivers/NI_NePA_driver.ko] undefined!

To make the file I just have the Makefile with: obj-m := NI_NePA_driver.o

I also get the following warnings during the build, but I don't see any relation:
