Hello, I'd like use ethoc driver for OpenCores MAC under Linux (2.6.33). I'm using OpenSparc T1 on FPGA. I have hardware device (OpenCores MAC) at address 0xFFF0C2C100. So I added device to platform bus with IORESOURCE_MEM (io memory space) at 0xFFF0C2C100. devm_ioremap_nocache() return OK but during ethoc driver initialization I have following messages: [ 36.003607] sun4v_data_access_exception: ADDR[000000fff0c2c000] CTX[0000] TYPE[0004], going.

Perhaps I need to add device to MD?
