I was told that Bosch's page for the C_CAN is here:

 http://www.semiconductors.bosch.de/en/ipmodules/can/canipmodules/c_can/c_can.asp

There it's also written for what bus interfaces the C_CAN is available for, e.g.:

  "The ASIC version is delivered with the AMBA APB bus interface from ARM."

On ARM we also have the AMBA bus abstraction in Linux, but I've never
worked with it. IIRC Wolfram (Cc'ed) has recently touched it.

which is obviously used in the "Platform Controller Hub" eg20t.

But in the pch, they've attached the AMBA to the PCI bus.

Ah, right. Anyway, with that driver we are prepared to handle other bus
interfaces by adding another bus-sensitive driver in
"drivers/net/can/c_can".
