Since the PCIe reset occurs before the MUX switch selection, please reset the PCIe root port using the U-Boot commands provided below.
U-Boot commands:
gpio clear gpio@ff0a000040
gpio set gpio@ff0a000040
After performing the reset, please verify PCIe device detection in the kernel by running the lspci -vvv command.
Incase, if this needs to be fixed permanently; please connect with iWave representative for the FSBL patch and create the binary which will avoid the use of PCIe reset command in U-Boot.
