The motivation is reduction of SPL code size.
Pali started working on something different (adding support for higher
baudrates to kwboot, so that a bricked board can be booted over UART
faster), and he is still working on it, but when he started studying the
kwbimage/kwboot code and A38x documentation, he noticed that these
things could be improved, so first he did this series.

You are right, the subject of the series could have been better. I
shall change it in v2.

OK.
