it looks like the above add logic handled bootargs well.

is this logic support the use case of appending existing bootargs from env
and handle the one mentioned in
[1] for simulation of vendor bootloader behavior to append some
androidboot.* bootcmd to formulate a new bootargs? Or is this series
complementary to [1] so as aimed to "move" androidboot.* only to
bootconfig? If this [1] user case is covered then I am very happy to stop
[1] if this series can have same result.

Btw, I am wondering if this series assumed Androidboot v4 only, so kernel
ver must >= 5.4 and enabled with bootconfig. Since then bootconfig can be
unlimited to it's length. So all predefined androidboot.* from bootloader,
can now move out, and no need of default bootargs in env file any more.

And how about those Androidboot v2 case?
