Thank you for your reply! I actually meant to write hip04 instead of hip05,
so I was only asking about the two 32-bit targets. I would expect that
hip05 still has a few users, but wouldn't mind removing that as well if you
are sure there are none.

Since Zhen Lei is starting to upstream Kunpeng506 and Kunpeng509
support, can you clarify how much reuse of IP blocks there is between
hip04 and those? In particular, hip04 has custom code for (at least)
platmcpm, clk, irqchip, ethernet, and hw_rng, probably more as those
were only the ones I see on a quick grep.

If we remove hip04, should we remove all these drivers right away,
or keep some of them around?
