Hello.
I am wondering if you can make sections of the gumstix "cs" v2 driver infrastructure public.
I do not know what "cs" is but I do know from it's presence in platform/pxa/tools/machines.py that it is an example of using multiple SFRs for one single v2 driver (which is what I need, too). My current approach of using L4 calls into the kernel to access range 2,3,4 has some potential issues, and I would like to have a backup.
I would like to understand all of the pieces involved in forwarding from the vcs server to the v2 driver multiple memory sections, so I would be satisfied to see an example on how to:
- properly obtain in the server ("vcs/cs") the memory range resources from the build system
- properly get the vbase of the ranges into the v2 driver via the device_setup_impl() for loop
- make a (working) dx
file that defines multiple xml mem objects/memory ranges and use it
If this can be made available it would be great, if not, please do not leave me hanging for weeks.
Thank you,
Gabi Voiculescu
