Kumar,
If I understand you correctly you have both an embedded/localbus EHCI
core and EHCI on the PCI bus. If this is the case then you could clone
ehci-hcd.c and use it as the basis for a driver for the embedded EHCI
core. Instead of including ehci-pci.c in the cloned code you would
include the platform specific code for your embedded EHCI. You would
need to change the "Kconfig" file and "makefile" in drivers/usb/
host to
compile the module for the embedded EHCI under a different name.
Thanks. I was looking for a solution that we could push upstream. I
can handle hacking it so it builds :)
One possiblity would be to move the code related to module_init/
module_exit into their own files that get build as separate objects
from ehci-hcd.c.
I was trying to build the USB EHCI host controller support as modules
for a PowerPC 834x which also has an embedded EHCI (and PCI enabled).
I get the following build error:
In file included from drivers/usb/host/ehci-hcd.c:895:

Which makes sense based on how ehci-hcd.c includes "ehci-fsl.c" and
"ehci-pci.c". I was wondering if there were an thoughts on how to
address this so I can build as a module..
