s/defaultly/by default/ I suppose. But what does that mean? Is it still
configurable, just now through some undocumented register? If that
register still exists, does it now have a reset value of all-ones as
opposed to the ls1021 case? If it's not configurable, then describing
the situation as "by default" is confusing and wrong, it should just say
"On LS1043A, LS1046A, SCFG_INTPCR is stored/read bit-reversed."

If I wanted my name splattered all over the files I touch or add, I'd
add it myself, TYVM. The git history is plenty fine for recording
authorship as far as I'm concerned, and I absolutely abhor having to
skip over any kind of legalese boilerplate when opening a file.
