Updating my Ultra96 setups from 5.4 to 5.10, I ran into a blocker:
Starting from this commit on, I'm no longer getting the kernel to boot
on both revision 1 and 2 (arm64 defconfig as reference). If I switch the
DTBs back before this commit, even a kernel from today's head is fine.
Further versions of potential relevance:
- PMUFW 2019.1 and 2020.2
- TF-A 2.3
- U-Boot 2020.10
What's missing? I suspect someone forgot to document a subtle dependency
of this change.
Thanks,
Jan
