We want to use generic 8250 debug_ll code to get DEBUG_UNCOMPRESS working and to simplify the code. The old debug_ll code is no longer needed and the machine ID based detection is no longer used. Note that for most part there's no need to keep DEBUG_LL enabled. We now have CONFIG_SERIAL_EARLYCON working very early as long as the kernel cmdline has "earlycon" in it and the board specific dts file has chosen configured with with the port using stdout-path.

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.
