Hi experts,
Trying to boot Rock4 SE of NVMe.
Soldered in the W25Q64FV for uBoot and flashed successfully using USB OTG. Connected to uBoot using serial console and everything seems to be working fine except that uBoot cannot see connected NVMe device. 2 NVMe drives I’ve tried, both are working as I can use them without problem when booted into OS from SD card.
In uBoot commands nvme scan, nvme info and nvme detail does not print anything and when booting into Linux I am seeing following call trace:

Do I miss device tree for my SBC?
Is there anything needs to be done to make it boot from NVMe drive?
Any information regarding this is highly appreciated
