The 98DX9236 has a single ARMv7 core. As such this resume control isn't
present on it. The 98DX3336 and 98DX4521 have dual ARMv7 cores and this
is used to boot the second core (SMP support is a little different
compared to Armada-XP).
In other words {98DX3336, 98DX4521} = 98DX9236 + an additional core. At
the switch packet processor level there are more differences but as far
as the kernel is concerned the only real difference is the number of cores.
