Keith,
thanks for the follow-up. I would have missed Wolfgang's email. I think we should take the discussion back to the mailing list.
The drivers should be in a common location and the BSP generation
mechanism should be used to overwrite these files for a given hardware design. That will always guarantee that the drivers matching the IP will be used.
Won't that mean that for any given design that uses a Virtex2/ppc405, the public U-Boot source tree will never be guaranteed correct? It sounds like the user would be required to maintain a locally modified U-Boot source tree for each design.
That sounds like a clumsy solution.
Could we just set up a common driver library and provide a mechanism to allow a particular board to configure the library for the particular IP versions used in the hardware design? Then the IP versions are specified in the board configuration file and you're done.
Note that no matter what approach is used, there is still the licensing issue. I cannot, for example, submit certain Xilinx driver files for inclusion into U-Boot that I need to support my board.
Are you planning to add a complete set of drivers to U-Boot?
Cheers,
- Peter
