Thomas Petazzoni 5a553d6ba1 PCI: mvebu: Use resource_size() to remap I/O space
Instead of hardcoding the remapping of IO_SPACE_LIMIT - SZ_64K, use
resource_size().

However, we cannot use just IO_SPACE_LIMIT, because pci_ioremap_io() has
a bug and doesn't allow remapping the last 64 KB before IO_SPACE_LIMIT,
so we ensure that we do not exceed this limit. When the pci_ioremap_io()
issue is fixed, this work around can be dropped.

Note that this workaround already existed, since we were mapping only
up to IO_SPACE_LIMIT - SZ_64K.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
