Yes, better leave it all in mach-bcm. You really shouldn't need much
code at all that is soc specific, so adding new directories is not
encouraged. We have some platforms that need no code at all, and on
arm64 that is required.

Isn't Northstar also IPROC? That one didn't seem to need the symbol.

Could you make ARCH_BCM_IPROC a silent symbol that is just selected
by each SoC family specific symbol?
