Yes: The generic Makefile.inc code in arch/x86 creates a coreboot.pre1 with the 
cbfs-files-y data.
Makefile.bootblock.inc then adds the romstage and calls the result 
coreboot.pre.
Makefile.bigbootblock.inc has nothing to do in that intermediate step from 
.pre1 to .pre, but to keep the dependency graph identical, we need to copy the 
data around.

- The coreboot.pre1 rule is now generic code.
- The coreboot.pre rule is bootblock/bigbootblock code.
- The further processing (coreboot.pre -> coreboot.rom) is generic code again.

This used to be:
- The coreboot.pre rule is bootblock/bigbootblock code (and the bootblock code 
uses .pre1 as intermediate step)
- The further processing (coreboot.pre -> coreboot.rom) is generic code.
