Yes, as each {GPMC_BCH_RESULTx_i} group is incremented by 0x10,
so I aligned the last address to 0x380 boundary. Hope leaving room for
extra 4 bytes (0x380 - 0x37C) will not matter much?
All platforms from OMAP4 onwards share the same version of GPMC engine.
So this remains consistent. Only OMAP3 has older version of GPMC engine
which has register-space till 0x2d0.
