In order to create a proper PCI driver for the IXP4xx we need to make the old PCI driver and its reliance on <mach/io.h> optional. Create a new Kconfig symbol for the legacy PCI driver IXP4XX_PCI_LEGACY and only activate NEED_MACH_IO_H for this driver. A few files need to be adjusted to explicitly include the <mach/hardware.h> and <mach/cpu.h> headers that they previously obtained implicitly using <linux/io.h> that would include <mach/io.h> and in turn include these two headers. This breaks our reliance on the old PCI and indirect PCI support so we can reimplement a proper purely DT-based driver in the PCI subsystem.

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.
