Hi, I have tried applying these patches to the v5.6.16 yocto kernel
supplied for the Icicle board. I've assumed this is a v5.9 patch set
as they don't apply cleanly to v5.6.16 so rebased up to v5.9
The PCie is failing to initialise on the icicle board. Is there
anything else needing to be done to get it working on this board?
