If developers are interested in bcm2712/RP1 or actually want to work on =
it, I could provide resources/infos for it.
If using u-boot the current status is reworking the pcie driver =
respectively implement the rp1 mfd =E2=80=A6
It`s quite new to have netboot possibility , (while quite everything is =
unofficial for now, even in u-boot & mainline tux kernel)
To say it simple: not ready for users but O.K. to start developing
