Yes. Indeed.
I'm trying to add pci2.0 and it looks i meet the same problem probably.
I backported (from well working neggles quartz64pro repo I assume):
https://github.com/neggles/linux-quartz64/commit/2ad84e89fc75b82c783345b72c97f5d7e3d45723
https://github.com/neggles/linux-quartz64/commit/4ac44c2b53758eca671d695d19b456d1849d7e14
https://github.com/neggles/linux-quartz64/commit/714c5e01d8f0f73b3a49cbdee29e3ffe0f3353dd
https://github.com/neggles/linux-quartz64/commit/64971f9c85f27e29c44b31a0c326ea4bb8ec3c56
then i added rock5b pcie dt enablements (basing on radxa BSP):
https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.2/files/1058-arm64-dts-rockchip-enable-pcie-rock5b.patch
this gives me quite clean 6.2 mainline boot log with hang at pcie2 init (pls see below)
I assume https://github.com/neggles/linux-quartz64/commits/linux-quartz64 repo works well on Quartsz64 board - so I indirectly assume above backports should give us working pice2.0.
It fails on rock5b - so I conclude: issue/error is on my side and is related to my rock5b specifics.
Unfortunately I don’t owe Quartz64 board so can't verify correctness of my backports by testing on Quartz64pro.
I’m curious about opinion of smarter than me guys…
