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

[Alexandre Ghiti]

This issue seems to have a fix in Linux, which is nice since it does not
depend on u-boot at all:

https://patchwork.kernel.org/project/linux-
riscv/patch/20220318152430.526320-1-ben.dooks at codethink.co.uk/

I'll give it a try.

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.
