I already surrendered and created (hacked) a read/write driver, which let me
use the old userspace drivers I'm trying to port (with some changes of
course). This was way faster than un

I don't know powerpc in general nor ppc405ep in detail but IIRC arm has
problems if some memory is mapped twice. Might this be the probl

As an aside, you sure you want to do this anyway? I'd suggest that you
just do a gpio chip driver for this, tie it in to gpiolib and use the
gpiolib user interface (which IIRC has only made it as far as -mm but

Maybee, the emac0 (0xef600800) and emac1 (0xef600900) get mapped as well,

Hi,
I'm unable to get UIO working on the ppc405ep onchip registers (e.g. gpio/iic)
however it's working fine on peripherals.
It seems to me to be a problem with UIO on powerpc, because if I change the
address (and nothing more) to point to a external FPGA it's working fine.
I also tried the gene
