Patrick Rudolph aae6e9cfe9 mainboard/lenovo: Add new port L520
Add support for Lenovo Thinkpad L520.

The files are generated by autoport,
and are successfully tested on the board.

L520 has got 4MiB flash chip, that contains a "slim" ME
with 1.2MiB only. The flash IC has to be desoldered, as
it won't be accessible in circuit. It is located on top
of the mainboard right under the touchpad.

Test-setup:
Extract the following blobs from vendor BIOS:
* Intel Flash Descriptor
* Intel Management Engine
* Intel VBios

The laptop has been externaly flashed. It was able to
turn on the display and load SeaBIOS.
Latest debian has been booted from harddisk.
Latest fedora has been booted from USB flash drive.

The following hardware has been tested and is working:
* Display using Option Rom
* PCIe wifi
* Ethernet
* Keyboard, trackpoint and touchpad
* Some Fn functions keys
* Volume Keys (except mic mute)
* Status LEDs
* Audio (headphone jack only)
* USB ports
* Native raminit dual channel (2 DDR3-1333 DIMMs tested)
* SATA cdrom
* SATA harddrive

Broken:
* Some Fn functions keys
* Microphone mute button
* Speakers (but headphone jack gives sound)

Untested:
* Expansion slot
* SD card slot
* Docking station
* Native gfx init

The EHCI debug port is the first one on the right side.
