Can you please describe how this bootconstraints core integration is
simpler than a "run things at max performance until late kernel init",
which could be triggered by a simple initcall similar to what is done
for clocks and regulators?
To me the bootcontraints stuff looks like a fairly complex solution and
your use-case doesn't even sound like you strictly want to keep a
bootloader configuration, but rather run things at max performance
until you are reasonably sure that you got all the necessary bandwidth
requests.

Lucas
