This driver enables the LPC snoop hardware on the ASPEED BMC which generates an interrupt upon every write to an I/O port by the host. This is typically used to monitor BIOS boot progress by listening to well-known debug port 80h. The functionality in this commit just saves all snooped values to a circular 2K buffer in the kernel, subsequent commits can act on the values to do things with them.

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.
