There are two UART ports on Armada3700. The second UART is based on the first one, plus additional features, but it has a different register layout (some bit fields are also moved inside the registers). Clearly separate register offsets and bit fields that differ between the standard and the extended IP. Access them in a generic way. Rename the defines with the "STD" prefix for future distinction with "EXT" defines. Point to these defines in the main driver data structure. The early console only uses the standard port (not extended).

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
