Hello build bot (Jenkins), Angel Pons,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/59704

to look at the new patch set (#11).

Change subject: mb/dell: Add Latitude E6400
......................................................................

mb/dell: Add Latitude E6400

Mainboard name is Compal JBL00. This is based on the GM45/ICH9M chipset
and uses DDR2 RAM. The EC is a SMSC MEC5035 which has internal flash, so
there's no issue about making sure to include the EC firmware in the
BIOS region. This only supports the variant with integrated graphics
only, the version with a discrete Nvidia Quadro NVS 160M is not
supported.
This port was based on the Lenovo T400 port.

Working:
- USB EHCI debug (lower USB port on right side)
- Keyboard
- Touchpad/trackpoint
- VGA
- Displayport
- ExpressCard
- Audio
- Ethernet
- mPCIe WiFi
- mPCIe Bluetooth (uses USB)

Not working:
- Brightness hotkeys
- Physical Wireless switch
- SD card slot: Linux outputs an "irq 18: nobody cared" message when
  inserting a card, after which it disables the IRQ

Unknown/untested:
- Dock
- Smartcard (slot and contactless)
- Firewire
- eSATA
- TPM
- Battery (my battery is at the end of its lifespan)
