Jiaxun just made changes to the 2E/2F code just a couple of weeks ago to
separate it from other Loongson64 support & clean it up - he also
indicated at the same time that he intends to contiue maintaining this
code [1].

Sadly "quirks" like this aren't solely the domain of Loongson 2E/2F
machines, so this isn't an unusual burden.

I disagree - Jiaxun says he's happy to maintain the platform & has
recently been working on it. I'm not going to remove it & deny him that
chance. If it does indeed become unmaintained then sure let's drop it,
but that doesn't seem to be the case here.
Thanks,
Paul
