Hi Phil,

A clean 5.15.45 boots cleanly, whereas a downstream kernel shows the static key warning (but it does go on to boot). The significant difference is that our defconfigs set CONFIG_RANDOM_TRUST_BOOTLOADER=y - defining that on top of multi_v7_defconfig demonstrates the issue on a clean 5.15.45. Conversely, not setting that option in a downstream kernel build avoids the warning
Ah, that makes sense. Note that I've got a patch out for changing that defconfig as well to be Y, which means the CI will catch this sort of thing in the future.
