Hi Jon, David and others,
I made some changes in my FDT generator. Here is the output for my testing platform.
Could you check this generated DTS file?
I would like to push the similar file with Microblaze kernel. (I'll do more generic DTS file with generic name and remove some unsupported peripherals)
For Steve: I'll send to you these changes later.
Thanks,
Michal Simek
