[Bug 1965321] Re: u-boot 2022.01+dfsg-2ubuntu1 breaks nvme on RISC-V unmatched board

[Heinrich Schuchardt]

My Unmatched board has /boot on NVMe and distroboot via extlinux.conf
works fine.

Please, describe your set-up. Where is your /boot directory? On MMC or
on NVMe? Maybe we have to add 'pci enum' to preboot if this is needed to
preconfigure PCI.

Title:
  u-boot 2022.01+dfsg-2ubuntu1 breaks nvme on RISC-V unmatched board

Status in u-boot package in Ubuntu:
  Incomplete

Bug description:
  When booting a jammy image on the SiFive Unmatched board, the nvme
  disk do not appear whereas by simply replacing u-boot with the
  previous version 2021.07+dfsg-0ubuntu8 works fine.

  Could be related to upstream commit
  a398a51ccc68c0a7aee14f8328dc86a1a4cfba85 ("pci: Work around PCIe link
  training failures"), I have to try.

  This does not look related to opensbi as both versions were built
  against the same opensbi version.
