Thanks, I was unable to boot bsd.rd, but setting up a system on a SD card
and copying the dtb to the efi partition worked out and gave me a booting
system. Well, most of the time it is booting. Sometimes the boot ends in
input/output errors. Is there any smart way to put the system on NVMe
while u-boot can't boot from it yet without having the root partition on
SD card?
Just for the record, the following patch for ports sysutils/dtb will not
change the console speed during the boot process and in addition will
enable the pcie port:
