No, I don't have such per-SoC symbols.

I only have ARCH_UNIPHIER, for the whole UniPhier SoC family.

We no longer #ifdef <SOC_THING> in C sources.

The only difference among SoCs is, which drivers should be enabled.

All SoCs in UniPhier family share the multi-platform kernel image,
so I think, this way is reasonable enough.
