To date this driver has relied on prevous state from out of tree hacks and vendor u-boot trees in order to have the host be able to access data over the LPC bus. Now we explicitly enable the AHB to LPC bridge and FWH cycles from when the user first configures the address to map. We chose to do this then as before that time there is no way for the kernel to know where it is safe to point the LPC window.

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.
