Subject: [PATCH 2/3] PCI: iproc: fix invalidating PAXB address mapping
Date: Thu, 26 Mar 2020 12:37:26 +0530	[thread overview]
Message-ID: <1585206447-1363-3-git-send-email-srinath.mannam@broadcom.com> (raw)
In-Reply-To: <1585206447-1363-1-git-send-email-srinath.mannam@broadcom.com>

From: Roman Bacik <roman.bacik@broadcom.com>

Second stage bootloader prior to Linux boot may use all inbound windows
including IARR1/IMAP1. We need to ensure all previous configuration of
inbound windows are invalidated during the initialization stage of the
Linux iProc PCIe driver. Add fix to invalidate IARR1/IMAP1 because it was
missed in previous patch.

Fixes: 9415743e4c8a ("PCI: iproc: Invalidate PAXB address mapping")
