[Qemu-devel] [PATCH] PCI: PCIe access should always be little endian


From: Matt Redfearn
Subject: [Qemu-devel] [PATCH] PCI: PCIe access should always be little endian
Date: Tue, 15 Aug 2017 15:44:17 +0100

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.
