recently we wanted to update xilinx intc driver and we found that function
which we wanted to remove is still wired by ancient Xilinx PowerPC
platforms. Here is the thread about it.

I have been talking about it internally and there is no interest in these
platforms and it is also orphan for quite a long time. None is really
running/testing these platforms regularly that's why I think it makes sense
to remove them also with drivers which are specific to this platform.

U-Boot support was removed in 2017 without anybody complain about it

Based on current ppc/next.

If anyone has any objection about it, please let me know.

This looks reasonable to me as well, in particular as the code only
supports the two
ppc44x virtex developer boards and no commercial products.

It does raise a follow-up question about ppc40x though: is it time to
retire all of it?

Who knows?

I have in possession nice WD My Book Live, based on this architecture, and I
won't it gone from modern kernel support. OTOH I understand that amount of real
users not too big.

+Cc: Christian Lamparter, whom I owe for that WD box.

According to https://openwrt.org/toh/wd/mybooklive, that one is based on
APM82181/ppc464, so it is about several generations newer than what I
asked about (ppc40x).

Ah, and I have Amiga board, but that one is being used only for testing, so,
I don't care much.

I think there are a couple of ppc440 based Amiga boards, but again, not 405
to my knowledge.
