[Query] Direction of adding arm64 support to PCIe designware driver

[Jisheng Zhang]

Hi all,

Currently, the pci designware driver still lacks of arm64 support and I noticed
that many works are done to achieve this goal.

Some patches are merged and some are under discussion. And Per my understanding, 
even w/ these patches merged, the driver still doesn't support arm64. Could you
please kindly point out the direction to add arm64 support to the PCIe
designware driver?

Thanks in advance,
Jisheng
