That is up to you.

If you do lots of small patches with good comments, you probably can
do it in Linux. But you need to convince reviewers you are not
breaking backwards compatibility.

I think the bootloader change is simpler. But i've not worked on
bootloaders for a long time.

You will do this anyway. However, just so that backwards comparability
gets tested all the time, i would suggest you only change mac0 and
mac3. Leave mac1 and mac2 with old settings, and add comments that old
values are being used for testing, and they should not be cut/paste
into new .dts files. And add a comment that mac0 and mac3 require the
new bootloader, if you decide to solve it that way.
