[PATCH v3 0/2] PCI: imx6: Correct the epc_features of i.MX8M EPs

Posted by Richard Zhu 3 months ago

IMX8MQ_EP has three 64-bit BAR0/2/4 capable and programmable BARs. For
IMX8MQ_EP, use imx8q_pcie_epc_features (64-bit BARs 0, 2, 4) instead
of imx8m_pcie_epc_features (64-bit BARs 0, 2).

For IMX8MM_EP and IMX8MP_EP, add fixed 256-byte BAR 4 and reserved BAR 5
in imx8m_pcie_epc_features.

Main changes in v3:
Seperate the patch into two commits and update the commit logs refer to
Bjorn's suggestions.
v2: https://lkml.org/lkml/2025/6/17/267

[PATCH v3 1/2] PCI: imx6: Correct the epc_features of IMX8MQ_EP
