[PATCH 0/2] make PCIe DMA work on Broadcom BCM2711

[Md Rayhanul Islam]

Hello,

Thank you for the detailed review. I am reworking the series as an RFC for
the EAL DMA API and PCI bus hook, with igb as the first user.

DMA properties now come from each device’s host bridge, and cache handling
is in EAL. I will also revise RX buffer reuse, TX completion, and
descriptor ownership, and add separate burst functions for non-coherent DMA.

I will also remove the extra guide and shorten the comments.

Best regards,
Rayhan
