I don't know a thing about the SCCs in the MPC8260, but you may want to
have a look at the Cyclades PC300 driver in the kernel. It does HDLC
(but I don't remember whether it's the PC300 driver or a generic HDLC
driver in the kernel). What HDLC do you wnat to implement? There is no
generic HDLC per se, but different framings using a HDLC-like framing.
Examples would be Cisco's IP over HDLC, or PPP.

For Cisco's HDLC, I added IP address autoconfiguration to the PC300
(submitted to the maintainer, but never found it's way into the official
