Still on Gerrit. ME downloader failed with HP update file, so let's just
use Lenovo's instead. Both contain identical ME8_5M_Production.bin files.

Tested and working:
* Native raminit with both DIMMs
* Libgfxinit textmode and framebuffer on both DisplayPorts and VGA
* External USB2 and USB3 ports: they all work
* USB 3.0 SuperSpeed (rear, 4 ports)
* Ethernet
* Mini-PCIe WLAN
* SATA: 2.5" SSD and optical drive bay
* SeaBIOS and GRUB (boot to linux)
* PS/2 keyboard and mouse
* S3 suspend and resume, wake using USB keyboard
* Headphone output, line out, internal speaker
* Wake on LAN
* Rebooting
* CMOS options & nvramcui

Untested:
* Line in, mic input
* MXM graphics card
* EHCI debug

Not working:
* Mini-PCIe USB: I couldn't get it working on vendor BIOS either, so
  maybe it just isn't present
* PS/2 keyboard wake from S3
* mSATA (I have no mSATA drives)

Tested with Johan Ehnberg (johan@molnix.com)

for example, files being downloaded have nothing to do
with the ME; they are merely compressed, and contain many
files in addition to it

rename board configs, and add to sources file the
t530/w530 boards

in some situations, the files weren't being downloaded
