Fill ESPRESSObin uart0 node with pinctrl information like in the Armada-3720-DB device tree (which uses the same node). Also explain how to enable the second UART port available on the headers. This second port is not enabled by default because both headers are dedicated to expose general purpose pins and remapping some of them to use the second UART would break existing users.

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.
