[PATCH 0/2] PCI: designware: improve iATU programming and usage
From: Jisheng Zhang
Date: Wed Apr 22 2015 - 09:01:58 EST
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@xxxxxxxxxxxxx>:
http://www.spinics.net/lists/linux-pci/msg40440.html
to change the iATU allocation: iATU0 for cfg and IO, iATU1 for MEM.
