Hello,
Can anybody please help me on writing the EHCI driver for platform
specific bus (non-PCI)? Please let me know are there any examples for
non-PCI EHCI.
If you need more info please let me know.
Thanks,

Hello All,
I'm using ARC's EHCI host controller and so I used Craig Nadler's patch.
But its not recognizing the host controller. Later I found that its an
on-chip host controller (i.e non-PCI).
How to add support for on-chip controllers? Can anybody help me how to
proceed from this situation? Are there any support for such controllers
already?
I'm using 2.4.25 kernel running on a processor based on ARM920T core.
(I understand you guys encourage using 2.6 kernel, but I have to work on
2.4 for now.)
Thanks,
Subhash
Hi Subhash, I did the same thing on a FreeBSD system using the arc core. The
problem is the details of your local bus will be extremely specific to your
platform, ASIC/FPGA core, and processor.
This is not an issue for linux-usb-devel, there is no way anyone can help
when you are using an ancient kernel interfacing via an unknown bus to your
custom hardware. What you have to do is UTSL and look at a comparable driver
and how it tied into the bus, for instance if you have an onchip ethernet
mac/phy and it is controlled by a kernel driver you can try and duplicate
how THAT driver hooks into the local buses and do likewise.
There is no easy, packaged way over this hurdle.
