At the time of the BCM281XX merge we considered that such directories would
mostly contain board files only, being these new entries DT based. Hence
the choice of mach-bcm to collect all of them.

I think you should then put this stuff there.

I'll throw also BCM476x (bcm4760 and bcm4761) on the table. These are ARM11,
single-core SoCs.

Can we agree on a nice naming so that we actually clarify this silliness?
