Custom Device Driver ioremap fails

Thanks in advance.

Using GSRD 14.1 - I've added a custom IP (that I had a device driver for in NIOS II uClinux).

The *.dts file says the address is: 0x1_0004_0000

In the nios2 I used to do the ioremap on the address in the nios2.h

So, I'm doing the ioremap on the address from the *.dts file and I get the following error.

So, what address do I use for the ioremap ?
