Cypress c67x00 Support?

Hi,

I have some questions about the Cypress c67x00 code that was posted a few days ago.
I got the many patches from the git (thanks Grant!), but I am wondering, 

How did you guys fix up the Kconfigs to work with the Xilinx Virtex-4 fpga?

My hw guys have put the cypress chip on 'the system ace'(OPB?) bus, a 16 bit bus, and I have the address to it.

But its definetely not PCI, and if you use a plain kernel tree like I have, I cannot access any features without turning on the PCI options.  Which of course fails, since I have no PCI parameters to feed the code.

Perhaps a better question is: Is this code intended for the Virtex-4?
If no, then I will have to fix it up.


Thanks,

Joe Robertson

You need to register the device on the platform bus.  Look at
arch/ppc/syslib/virtex_devices.c and
arch/ppc/platforms/4xx/xparameters/xparameters.h.  You need to fixup
your xparameters file to match up with the c67x00 registration in
virtex_devices.c. (hint: look at the XPAR_C67x00_USB macro)

Cheers,
