<div class='commit-subject'>ARM: mvebu: map PCI I/O regions strongly ordered</div><div class='commit-msg'>In order for HW I/O coherency to work on Cortex-A9 based Marvell SoCs,
all MMIO registers must be mapped strongly ordered. In commit
1c8c3cf0b5239 ("ARM: 8060/1: mm: allow sub-architectures to override PCI
I/O memory type") we implemented a new function,
pci_ioremap_set_mem_type(), that allow sub-architecture code to override
the memory type used to map PCI I/O regions.

In the discussion around this patch series [1], Arnd Bergmann made the
comment that maybe all PCI I/O regions should be mapped
strongly-ordered, which would have made our proposal to add
pci_ioremap_set_mem_type() irrelevant. So, we submitted a patch [2] that
did what Arnd suggested.

However, Russell in the end merged our initial proposal to add
pci_ioremap_set_mem_type(), but it was never used anywhere. Further
discussion with Arnd and other folks on IRC lead to the conclusion that
in fact using strongly-ordered for all platforms was maybe not
desirable, and therefore, using pci_ioremap_set_mem_type() was the most
appropriate solution.

As a consequence, this commit finally adds the
pci_ioremap_set_mem_type() call in the mach-mvebu platform code, which
was originally part of our initial patch series [3] and is necessary for
the whole mechanism to work.
