Hi,
I'm using bl31.bin to handoff control to a test app on the imx8QM MEK. A requirement of our BSP is the initialization of the PCIe controller on exit of the bootloader. Can anyone share the minimal config steps needed to make the PCIe active and enabled ? Is there some init code in SCFW, TF-A I can use to init the PCIe controller ? Thanks in advance.

Hi rkohli2000
one can look at uboot:
as driver is the same as for i.mx6q, use its examples:
