I went through several patches related to similar issues, and mostsuggest handling it on a SoC basis. The reasoning is that a system
may have an affected PCIe root complex while still having other
devices in the SoC that can, or even require, 64-bit accesses.

The following are some of the patches that I had looked into:
https://lore.kernel.org/lkml/20210226140305.26356-2-nsaenzjulienne@xxxxxxx/T/#u

https://lore.kernel.org/linux-arm-kernel/c188698ca0de3ed6c56a0cf7880e1578aa753077.camel@xxxxxxx/T/#u

Can you please suggest any alternate methods that we could use to
handle this in a more generic manner instead of making it Soc-specific.

Thanks,
