This looks a bit funny: all other entries have the "const" last, and
use it for the
SoC number. May be correct, though.
To clarify, this is an extension board that can fit both the [HM]3ULCB
boards (actually also the new M3NULCB, I think).

This being Kingfisher?

Correct.

I wrote this based on dts files in the tree. There's 2 combinations that I see:

"shimafuji,kingfisher", "renesas,h3ulcb", "renesas,r8a7795"
"shimafuji,kingfisher", "renesas,m3ulcb", "renesas,r8a7796"

The schema allows 4 combinations (1 * 2 * 2). I have no idea if the
other combinations are possible. If not, then we could rewrite this as
2 entries with 3 const values each.

I expect there will soon be a third one:

    "shimafuji,kingfisher", "renesas,m3nulcb", "renesas,r8a77965"

Technically, {h3,m3,m3n}ulcb are the same board (although there may be
minor revision differences), with a different SiP mounted.
But they are called/marketed depending on which SiP is mounted.

And on top of that, you can plug in a Kingfisher daughterboard. Could be an
overlay ;-)

Gr{oetje,eeting}s,
