The outbound iATU programming functions are similar, so PATCH1 consolidates them into one.
Most transactions' type are cfg0 and MEM, so current iATU usage is not balanced. PATCH2 adopts idea from Minghuan Lian <Minghuan.Lian@freescale.com>:

to change the iATU allocation: iATU0 for cfg and IO, iATU1 for MEM.
