88DE3010 is based on ARMv5 and is too old, I bet there are no real users now. Can we
remove it?

BG2(B0), BG2(A0) and BG2(Z1) are both called 88DE3100, Armada 1500. They are
just different Step versions. And BG2(Zx) BG2(Ax) are rarely used outside marvell
Mostly used version is BG2(B0)

(If you leave a blank line between my message and your reply it is much
more easy to find)

I see Marvell also removed it from DE product line. So, I agree, let's
get rid of it.

Yeah, I was maybe just making it up, as you weren't allowed to clarify
it before. I'll remove the stepping from the design name.
