[okl4-developer] Some question about "machine.py" setup files

[Qmo (Yi-Sheng)]

Hi Geoffrey,

Thanks for your reply, can I ask another question.
How did the memory_timer = [(0x51000000, 0x51001000)] ( memory_serial etc...
)set up for the platform?
How to generate the address mapping between the platform and OKL4?
Thank you very much.

Best Regards,
Yi-Sheng
