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

I'm installing the u-boot to the NVMe drive as the CM4 I have doesn't have eMMC And CM4 only have 1 PCIe lane so I can't add another PCIe device
I think Home Assistant OS 9.5 which is based on u-boot 2022.1 works with my hardware, as the green LED is blinking. But I'm not sure as it seems that their rpi4 build doesn't enable serial console.
Thanks Ignatius
I've got serial out working with Home Assistant OS 9.5: https://github.com/home-assistant/operating-system/releases/tag/9.5 and I can confirm that their u-boot works with my hardware:

I can't press any key to enter the u-boot prompt, so I can't run nvme scan command. But this show that there's a certain combination of: - U boot version - U boot build config - RPI4 firmware
that works

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

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
