orion5x is still some time away from being included in mvebu, 3.16 at
the earliest, so it will have to stay separate anyway.

My hope is really that we get very little overhead in enabling
multiplatform on mvebu compared to a orion5x or kirkwood standalone
configuration, so depending on what the platforms have you could
end up with e.g. a 1.5MB "mini" multiplatform kernel that includes
all machines that have 2MB or less for their kernel partitions and
a "everything included" multiplatform kernel for the machines with
larger partititons. For instance kirkwood-rd88f6281 has a 2MB
uImage partition and everything else seems to have at least 4MB.
