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. https://lore.kernel.org/linux-next/48d3232d-0f1d-42ea-3109-f44bbabfa2e8@xili...
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 https://github.com/Xilinx/u-boot-xlnx/commit/98f705c9cefdfdba62c069821bbba10...
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.
Ah, and I have Amiga board, but that one is being used only for testing, so, I don't care much.
The other ppc405 machines appear to have seen even fewer updates after the OpenBlockS 600 got added in 2011, so it's possible nobody is using them any more with modern kernels.
I see that OpenWRT removed both ppc40x and ppc44x exactly a year ago after they had not been maintained for years.
However, 44x (in its ppc476 incarnation) is clearly still is used through the fsp2 platform, and can not be deprecated at least until that is known to have stopped getting kernel updates.
