Hi Andrey,

We have taken a log of Bootinfo script as below. Non Volatile Memory
Express(NVMe) is PCIe based
controller. In Linux kernel for this controller there is a driver
module present with name nvme.ko. We will
start looking at core.img. There is no BIOS support for this device as
it is a PCIe plug and play
device. We have our Legacy OptionROM support for booting from this controller.
