DPL and DPC are tied to the SERDES config:
if [ "x${SERDES:0:3}" =3D=3D "x13_" ]; then
=09DPC=3Ddpc-dual-100g.dtb
=09DPL=3Ddpl-eth.dual-100g.19.dtb
fi
if [ "x${SERDES:0:2}" =3D=3D "x8_" ]; then
=09DPC=3Ddpc-8_x_usxgmii.dtb
=09DPL=3Ddpl-eth.8x10g.19.dtb
fi
if [ "x${SERDES:0:2}" =3D=3D "x4_" ]; then
=09DPC=3Ddpc-8_x_usxgmii.dtb
=09DPL=3Ddpl-eth.8x10g.19.dtb
fi
if [ "x${SERDES:0:3}" =3D=3D "x20_" ]; then
=09DPC=3Ddpc-dual-40g.dtb
=09DPL=3Ddpl-eth.dual-40g.19.dtb

Right now we're mostly working with 8_5_2, but I know Jon is doing some mor=
e work to get things sorted. IIRC he's waiting on some PRs to get merged up=
stream in the Tianocore EDK2 repos.
I think someone was working on porting the lx2160a_uefi repo but I haven't =
heard much about it in a while.
If you're a Discord user, Jon Nettleton - one of SolidRun's engineers - and=
a handful of others who are playing with Honeycombs in different capacitie=
s are also collaborating here: https://discord.gg/tgHuG4Cq
