you're welcome to try and fix nvme support in the upstream-ish uboot, contributions will be accepted  until that's done (or another bootloader pops up), it'll be a choice :/
I was suspecting that it's uboot...
As to the contributions - it's well beyond my competences unfortunately

the BIG cores are online on my device with CONFIG_ARM64_ERRATUM_1319367=y. Tasks seem to be scheduled to them as well. Also corrupted TLBs don't sound particularly fun to me. Are you sure I should disable that option?
unexpected! so I built a kernel with this enabled and the two cores didn't come up, and specifically listed this erratum in error. rebuilding with the sole change of disabling the erratum brought the cores up. I AM using maxcpus=4 uboot option.
I used linaro arm 9.2 cross compiler on an amd64 system.
if this is working for you then the issue must be on my side. thoughts?
A recent systemd upgrade wanted to write into sysrq
Code: Feb 06 21:41:55 manjaro systemd-sysctl[267929]: Couldn't write '16' to 'kernel/sysrq', ignoring: No such file or directory
@ tsys, to make systemd happy, consider adding sysrq support into the default (manjaro) kernel
Code: manjaro:~$ zgrep -i sysrq /proc/config.gz
# CONFIG_MAGIC_SYSRQ is not set

Hm, agreed. The magic sysrq is actually super helpful when debugging crashes, too. My defconfig has it enabled, Manjaro does not though. Will probably be fixed with the next release now.

Hi,
I've a small update on headphone and speaker audio for all of you. https://gitlab.manjaro.org/tsys/linux-pinebook-pro does now feature control over the speaker amplifier and working headphone detection. Thus in tools like pavucontrol you can now select headphone output and actually have your speakers disabled.
Note that the kernel sound subsystem does not automatically disable the speakers when headphones are plugged in. However the headphone jack is exposed as an input device, thus an input daemon like acpid can be used for automatic switchover.

@ tsys excellent. thank you. I assume that the v5.5 branch has now merged with master? will the v5.5 branch continue separately?

Yes, I might still push more experimental changes to the v5.5 branch. Only code I deem stable enough is pushed to the master branch
perfect. thanks for the clarity. (and thank you!)
so an update on the ARM erratum 1319367 situation.
A> kernel 5.5 with 1319367 disabled and maxcpus4 = boots "normally"/quickly
B> kernel 5.5 with 1319367 enabled and maxcpus4 = boots "normally"/quickly, and big cores disabled
C> kernel 5.5 with 1319367 enabled and without maxcpus4 = boots "slowly", and big cores enabled (boot takes ~30sec longer)
i am using luks with password prompt
B> dmesg | grep CPU
