From the hardware user manual: "The FPA is a unit that maintains
pools of pointers to free L2/DRAM memory. To provide QoS, the pools
are referenced indirectly through 1024 auras. Both core software
and hardware units allocate and free pointers."

This looks like a possibly similar implement to what
drivers/net/ethernet/marvell/mvneta_bm.c, can you see if you can make
any use of genpool_* and include/net/hwbm.h here as well?
