When building OpenRISC PCI, which has no ioport_map(), we get the following
build error:
lib/pci_iomap.c: In function 'pci_iomap_range':
CC drivers/i2c/i2c-core-base.o
./include/asm-generic/pci_iomap.h:29:41: error: implicit declaration of function 'ioport_map'; did you mean 'ioremap'? [-Werror=implicit-function-declaration]
29 | #define __pci_ioport_map(dev, port, nr) ioport_map((port), (nr))
| ^~~~~~~~~~
lib/pci_iomap.c:44:24: note: in expansion of macro '__pci_ioport_map'
44 | return __pci_ioport_map(dev, start, len);
| ^~~~~~~~~~~~~~~~
Add a NULL definition of __pci_ioport_map() for architectures that do not
support ioport_map().

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.
