u-boot work in progress

[colemickens]

It's "close"-ish, I guess. But still doesn't want to really boot off USB, seems to hang? Not sure, quick braindump.

This is using a hacked up defconfig, starting from the rock5b dtb.

It gets closer than when I tried to use the evb-rk3588_defconfig from the collabora repo.

I can get it to see some USB devices, like it will see a certain ethernet adapter and complains about its MAC address, but it doesn't seem to actually try to net boot from it.

[colemickens]

I'm guessing some surgery to extract the DTB from the good dump I got: https://github.com/colemickens/h96-max-v58-investigation/issues/5, decompile the dtb->dts and then mashing it up with the rock5 device tree could get me closer. Not sure I'm going to be able to do that before I have to leave this board behind again.

[colemickens]

note to self: try the rock5b defconfig, but point it at the EVB device tree instead and see where that goes.

fascinating work. far less expensive than the rk3588 'sbc's. Is this a rk3588 or rk3588s ?
