Hi,
I've had some recent success with my gru-kevin and wanted to update you on this. Long story short, I can boot from SPI flash and have the display, keyboard, eMMC, microSD card, USB disks all work (however with some hacks); but can't boot into Linux. Things seem to hang shortly after "Starting kernel..." but I don't know if something fails in U-Boot or if I get a kernel panic. (I still have no serial console).
I suspect you need the following patch [1], we had the same hang in Fedora and even with a serial console and a whole bunch of kernel debug it was difficult to get to the bottom of. Sadly the fix, whether this patch or another one is still not upstream.

There are three relevant branches on my GitHub repo now, please have a look. The first is for what I intend to send upstream soon enough. The other two include hacks and additional patches that build on top of the first, meant to improve things on a per-board basis:
https://github.com/alpernebbi/u-boot/tree/rk3399-gru-chromebooks https://github.com/alpernebbi/u-boot/tree/rk3399-gru-kevin https://github.com/alpernebbi/u-boot/tree/rk3399-gru-bobI have no idea if the gru-bob versions work. I just thought things I did for gru-kevin are applicable to it as well and decided I should include them in case anyone wants to test.
I also want to ask you some things I'm indecisive about, before posting the rk3399-gru-chromebooks branch as patches.
Most of the patches are small config and dts changes that I've grouped by whatever effect they have. Should I squash them into one commit each for config/dts?
Simon, I've edited some of your patches and kept you as author & sign-off. Are you OK with the edited versions, am I doing things right? See:
https://github.com/alpernebbi/u-boot/commit/8c658b7811f4324cd699bd035e802f93...
https://github.com/alpernebbi/u-boot/commit/c2c68f23e10a51b8d34c00764a33fc84...

Marty, your (second) chromebook_kevin support patch didn't have your sign-off. Is it OK to add it? See:
https://github.com/alpernebbi/u-boot/commit/4cee351e012dc26714640e868069b5cc...
I also think I should squash my gru-kevin changes into that commit, add a commit message about board status, and keep Marty as author & sign-off while adding myself as Co-authored-by & sign-off. Any better ideas on how to structure the patches?
Do both of you want to be in /board/google/gru/MAINTAINERS? I have three of us listed there right now, but no idea if that's fine with you two.
Hope you can spare time on this.
