It's quite possible to create one directory now, e.g. mach-bcm281xx, and
then when consolidation with other mach-bcm* happens, merge all those
directories into a single mach-bcm. I would tend to prefer (but only
lightly) using mach-bcm281xx now and then renaming later, unless you
plan on expanding the SoC support in the pretty near future.
