[ Upstream commita17ab7aba5] Add support for the AMD A85 FCH (Hudson D4) AHCI adapter. Since this adapter does not require the default 200 ms debounce delay in sata_link_resume(), create a new board board_ahci_no_debounce_delay with the link flag ATA_LFLAG_NO_DEBOUNCE_DELAY, and, for now, configure the AMD A85 FCH (Hudson D4) to use it. On the ASUS F2A85-M PRO it reduces the Linux kernel boot time by the expected 200 ms from 787 ms to 585 ms.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
