[U-Boot-Users] Linux port for MPC855T

Hi

I have newly subscribed to this mailing list. I notice that neither the
ppcboot nor the uboot lists are presently archived on Sourceforge, so I
cannot see how active the lists are. I wish to discuss Linux BSPs for
MPC855T. Is the uboot list appropriate for such discussion?

I am evaluating the use of Embedded Linux on MPC860 PowerPC,
specifically the MPC855T. I am currently requesting quotations from
Linux suppliers to port Linux to our 855T card. Currently, we run
VxWorks on this card so a VxWorks BSP is fully tested.

I know that a major part of the port will be programming the 855T's UPM
(User Programmable Machine) that is responsible for setting up memory
controller, CPU core etc. I would like advice on how to handle this.

- Should such setup be already available in an open source Linux MPC860
BSP?
- Should I try to make use of our existing BSP?
- Is it reasonable for the supplier to quote for BSP development or
should they be using open source code?

I will be grateful for any advice, as this is a very new area for me.

Best regards

David
