Boot from NVMe is broken with "upstream" u-boot and "upstream" kernel

[misuzu]

Here is my setup:

• u-boot from https://github.com/misuzu/u-boot/commits/visionfive2
  It's u-boot/u-boot@a169438 but with misuzu/u-boot@9c29cdd for the u-boot to actually work, USB patch (also tried without it - same issue) and misuzu/u-boot@355b187 to make it boot from NVMe.

• Linux kernel from starfive-tech/linux@64a6c57

• systemd-boot as bootloader

• NixOS

The problem:

I have my EFI partition on an SD card and the root ext4 filesystem on an NVMe drive. This setup works fine, the u-boot loads systemd-boot, it then loads the kernel, it does its thing, mounts root filesystem and starts systemd.

But, if I copy my EFI partition to an NVMe drive and eject the SD card or just run pci enum and then boot in u-boot, the Linux kernel won't be able to initialize NVMe.

tl;dr - initialize NVMe drive in the u-boot - kernel won't find it, don't initialize NVMe drive in the u-boot - everything fine.

Here are the logs:
efi_on_sdcard.log (working)

efi_on_nvme.log (fails)

sdcard-to-nvme_cut_diff.txt (the difference between the two, minus time)

The OS image and the u-boot files for testing can be found here.

Looks like the issue is gone with starfive-tech/linux@67e8df0 and misuzu/u-boot@0850e3a
