Subject: [PATCH v6 03/53] powerpc/PCI: Add IORESOURCE_MEM_64 for 64-bit resource in OF parsing
Date: Wed, 30 Sep 2015 22:52:37 -0700 [thread overview]
Message-ID: <1443678807-786-4-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1443678807-786-1-git-send-email-yinghai@kernel.org>
For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set
IORESOUCE_MEM_64 for 64bit resource during of device resource flags
parsing.
