First of all, the driver was parsing the 'dbi' register region as 'elbi'. This was due to DT mistakenly passing 'dbi' as 'elbi'. Since the DT is now fixed to supply 'dbi' region, this driver can rely on the DWC core driver to parse and map it. However, to support the old DTs, if the 'elbi' region is found in DT, parse and map the region as both 'dw_pcie::elbi_base' as 'dw_pcie::dbi_base'. This will allow the driver to work with both broken and fixed DTs. Also, skip parsing the 'elbi' region in DWC core if 'pci->elbi_base' was already populated.

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 reStructuredText 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.
