- useful for `collabora` and other experimental kernels, we don't want to have to add it to each individual board's KERNEL_TARGES one by one - but we don't want to allow typos in BRANCH to emit very strange unrelated errors

This hook is run when when we know the family uses mainline (does NOT set KERNELSOURCE),
|
|
but the family/board/hooks haven't determined a KERNELBRANCH (tag/branch/commit reference) yet.
|
|
All hooks are called in the usual order, the last one setting it "wins".
|
|
It is expected that hooks here are able to:
|
|
- if kernel in RC period, convert say 6.7 to tag:v6.7-rc7
|
|
- "lock" certain families (or all families) to a certain tag in a branch; say convert 6.6 to tag:v6.6.6
|
|
- change KERNELSOURCE to adapt to too-new -rc releases that haven't shown up in stable kernel git tree yet
