How about this approach: since the problem is the presence of CPU- (or Soc-)level elements in board-level config files, and since there are probably many other such items in board config files (CPU type in a SoC and HW IP configurations, for instance) then why not introduce some cpu-config and soc-config file which would group all those cpu- (resp soc-)level items, including any "#define CONFIG_ARCH_CPU_INIT", and replace these items in board config files with a single "#include "<cpu>-config.h" (or "<soc>-config.h")? This would significantly reduce board config file size.
Note that omap4/5 do something like this already and my hope is to do this for omap3/similar and make some other common files as well. It's not the top priority for me atm however...
