Hi Emil,

I've checked with our hardware team. BS01DCMA is indeed a module, so
the "board" wording in this series is wrong and I'll fix it in the next
version.

I'd still like to keep a single k3-bs01dcma.dts though. The module is
only used in the RV2768, and that carrier is essentially just cabling
to PCIe network cards. Those are found by enumeration and there's
nothing else on it for the K3 to control, so a
k3-bs01dcma-rv2768.dts would have nothing to describe.

Does that work for you?
