References: Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Hi David, I'm a little hesitant to mention this, because I have been flamed for referring to code in older kernels, but here goes :-) I developed an HDLC/PPP driver for kernel 2.2.5 for the MPC850. The code is GPL'd, so you are welcome to use it, or use at it as an example. I have been informed by people at other companies that this driver is used to interface to CISCO routers. It has been used on boards other than our own QS850. It makes use of the syncppp.c module in the standard kernel. I developed the HDLC portion for the SCC's. There is some porting work involved, because we use some subsystems we developed that have not been folded into the 2.4 kernel (namely I/O setup), but it should only be trivial work (we use Dan Malek's include files for CPM register definitions, Thanks Dan!). The source can be downloaded from ftp://qslinux.org, and there should be some documentation on http://qslinux.org. If you do port this code to Kernel 2.4 then let me know. Perhaps we can work together to get it folded into the latest PowerPC kernel for others to use, as there is interest in it from time to time.
