Hi Jisheng,
Sorry for my delay in answering, I was on holiday.
AFAIK there is no ready made version of the designware driver that will work for
arm64. Depending on your actual IP implementation, if is is SBSA compliant then
it should work with the generic host bridge driver rather than using the current
designware driver. If that doesn't fit your requirements then you will have to
update the existing driver to use the generic pci framework that arm64 needs.
Best regards,
Liviu
