Commite4ab08be5b("powerpc/isa-bridge: Remove open coded "ranges" parsing") broke PASemi Nemo board booting. The issue is the ISA I/O range was not getting mapped as the logic to handle no "ranges" was inverted. If phb_io_base_phys is non-zero, then the ISA range defaults to the first 64K of the PCI I/O space. phb_io_base_phys should only be 0 when looking for a non-PCI ISA region.

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.
