SSD is not working on T2080RDB

[VenkatVellanki]

Hello, 

I am working with T2080 custom board having ssd nvme connected to processor over pcie

I have successfully loaded uboot and linux into T2080 and able to see SSD getting enumerated in both uboot and linux

At Linux using lspci i am able to see the device enumeration as well but i am unable to access the SSD and it is not getting listed in cat /proc/devices

Below is the ERROR code obtained while booting Linux
