Compact Flash Disc with devb-eide?

Hi

I try to use a compact flash card with devb-eide on a MIPS embedded
system with an AMD AU1500 processor. In a start application the card is
enabled and the CIS can be read.
The CF I/O physical address space is 0xF00000000 (36 bit).
My question is how to call the block device driver.

I tried

devb-eide eide ata,ioport=0xf00000000,noslave

then the systems hangs.
Any idea?

Best Regards,
Joerg

The current version of the eide driver only supports 32bit addresses.
I will look into adding >32bit addresses.
