[SRU][J][PATCH 0/1] support PCI BARs larger than 128GB

[Bartlomiej Zolnierkiewicz]

BugLink: https://bugs.launchpad.net/bugs/2037403

[SRU Justification]

[Impact]

Current linux-bluefield kernel reports that PCI BARs larger than 128GB are disabled.

Increase the maximum PCI BAR size from 128GB to 8TB for future expansion.

[Test Plan]

Use updated kernel with PCI device with PCI BARs larger than 128GB.

[Where problems could occur]

No potential problems are expected.

[Other Info]

Testing has been provided by the customer. This patch is a cherry-pick from the upstream 5.18 kernel. It is intended for linux-bluefield kernel re-spin but it may be also suitable for the generic kernel (separate submission).
