Does Brahma15 identify the ARM-based members of the BCM7xxx family? I
ask since it's a little confusing knowing that there's some MIPs-based
BCM7xxx SoCs and this binding is specific to the ARM versions.  Could the
ARM-based members be enumerated explicitly by part number? e.g. BCM7445,
etc.

Along the same lines...Isn't this a little too generic for a compatible
string? If BCM7445 were the first in this family wouldn't brcm,bcm7445
be more appropriate given the compatible string naming guidelines?
