Properly propagate failure from mvebu_pcie_add_windows() function back to the caller mvebu_pci_bridge_emul_base_conf_write() and correctly updates PCI_IO_BASE, PCI_MEM_BASE and PCI_IO_BASE_UPPER16 registers on error. On error set base value higher than limit value which indicates that address range is disabled. When IO is unsupported then let IO registers zeroed as required by PCIe base specification.

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.
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.
