From: Ryder Lee <ryder.lee@mediatek.com> MediaTek's PCIe host controller has two generation HWs, the new generation HW has two root ports, it shares most probing flow with the legacy controller. But the read/write config space logical is different from the legacy controller. The per-port register must be touched for read/write config space, And the per-port register base are in separate address space.
Can you also include the new controller IDs ("MT7622/MT2712"?) in the
subject line of this patch?
Add support for new Gen2 controller which can be found on MT7622/MT2712.
