The new memory map is also used for 32-bit SoCs V5 (sun8iw12p1) and
newer. So this is not sun50i-specific, and I'd suggest SUNXI_GEN_H6 (or
even SUNXI_GEN_H6_V5). It is unfortunate there appears to be no name for
this family.

I would expect this to select SUN50I_GEN_H6.

Was this removal intentional? You later add a different value for H616 only.

This can probably be simplified to ARCH_SUNXI.
