This is a good question indeed. I have checked closer and this is what
documentation says
Documentation/admin-guide/kernel-parameters.rst
"
BOOT Is a boot loader parameter.

Parameters denoted with BOOT are actually interpreted by the boot
loader, and have no meaning to the kernel directly.
"

and that really doesn't fit, right? So I went to check the full history
git tree just to get to 2.4.0-test5 and no explanation whatsoever.
Fun, isn't it? ;)
