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

[Alexandre Ghiti]

Public bug reported:

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.
