It should be pci_1:0.0 I think

I don't know what is going on here. The PCI scan seems to show the wrong device, as you say. Perhaps it is a bug in the bcm controller driver?

I've not used the NVMe driver in U-Boot yet, but at least the PCI class and subclass ID seem to be fine AFAIT:
class code = 0x01 (Mass storage controller) sub class code = 0x08 programming interface = 0x02
Are other PCI drivers probed correctly, if you can test this on your board? E.g. an Intel E1000 PCIe board perhaps?
Added Bin, perhaps he has some further ideas.
Thanks, Stefan

Hi all,
I'm using U-boot 2022.07 from Yocto Langdale distribution, with the following NVMe related kconfigs manually enabled through menuconfig:
CONFIG_NVME CONFIG_NVME_PCI CONFIG_CMD_NVME
and logging turned into max
The SSD is Kioxia SSD, and it works with Pi 4 bootloader as I can boot Raspberry Pi OS from the NVMe drive.
U boot is installed in the fat32 partition in the NVMe SSD for this Yocto poky build.
When I boot to U boot prompt, I can see that the SSD is detected by pci U-Boot> pci long 0

but it doesn't show up in nvme scan or nvme info U-Boot> nvme info U-Boot> nvme scan
I know that U boot can boot from NVMe, as I can run Home Assistant OS that's based on U boot on NVMe drive. I just don't know if I missed a kconfig somewhere, or this U boot version haven't implement it
Can anyone help me with this?
Thanks Ignatius
