Hi Vivien

I've been looking at the Marvell reference code, in particular, the
function gfdbGetAtuAllCount().

The following device have 16 databases.

( DEV_88E6021 | DEV_88E6060 | DEV_88E6063 | \
DEV_FH_VPN | DEV_88E6083 | DEV_88E6183 | DEV_88E6093 | DEV_88E6061 )

The following device have 64 databases.
( DEV_88E6065 )

The following devices have 256 databases
( DEV_88E6095_FAMILY | DEV_88E6185_FAMILY )

And the following devices have 4096
( DEV_88E6097_FAMILY | DEV_88E6165_FAMILY | DEV_88E6\
351_FAMILY| DEV_88E6352_FAMILY )
