            Bug ID: 274484
           Summary: NVMe drive not working on RK3566 Rock 3C Model
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: arm64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: arm

Hi.
I'm trying to get NVMe driver working under this board. From the specs it's
very similar to Quartz64-B, which should have some support already in kernel
and also in DTS (PCIe is enabled in there).

I'm using FreeBSD 15.0-CURRENT #0 main-n265904-bb679b0c4909.
DTS used is the one from
https://github.com/warpme/minimyth2/blob/master/script/kernel/linux-6.5/files/0845-arm64-dts-rockchip-add-dts-for-rock3c.patch
(I've compared it with Quartz64-b and only some USB diffs are in there).

The effect is the same with this DTS and Quart64-b one.

Ethernet works, 2 USB works. Here are some logs from boot (if needed I can
provide full dmesg, I think this part is related to pcie):

I've checked the NVMe under Linux on the same board and it's working fine, the
specs are:
