Subject: [Qemu-devel] [PATCH] PCI: PCIe access should always be little endian
Date: Tue, 15 Aug 2017 15:44:17 +0100	[thread overview]
Message-ID: <1502808257-17395-1-git-send-email-matt.redfearn@imgtec.com> (raw)

PCIe busses are always little endian, so set the endianness of the
memory region to little endian rather than native such that operations
work as expected on big endian targets.
