issue about PCIE on board s32v234sbc:pcie can not work,"phy link never came up"

[kun_jia]

I'm trying to enable pcie support on s32v234sbc board, "Enable PCIE support" in menuconfig, details just list as follows,

run make menuconfig:

/@/-ThinkPad-E470:~$ make ARCH=arm64 CROSS_COMPILE=/path/to/your/toolchain/dir/bin/aarch64-linux-gnu- menuconfig

select orderly:

 Bus support->Designware PCI Core Supprt->Platform bus based Designware PCIe Controller;

 Bus support->Freescale S32v234 PCIe Host Controller

                    ->Ignore Freescale S32v234 erratum ERR009852

                    ->Freescale S32v234 PCIe DW DMA

saved and exist.

/@/-ThinkPad-E470:~$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-

build successfully.

When the system boots I saw such log:

This bsp version is 18.0 hf1. 

Could you give me a favour whether I had lost/failed in some config or not.

Thanks!
