coreboot

This Haswell board comes with a Samsung PCIe AHCI SSD on a autoport Unsupported PCI device 8086:0d01 (Apple Slot) which is probably muxed with the Thunderbolt controller Unsupported PCI device 8086:0d05. There is also no native intel SATA controller available on this board.

Adding RegisterPCI(0x8086, 0x0d0c, GenericPCI{}) to line 141 in haswell.go within /* CPU HD Audio */ fixes the 8086:0d0c device not being Unsupported.

However I have no idea how to add those Unsupported PCIe 00:01.0 / 00:01.1 0d01 / 0d05 devices to the code, but I was able to remove the SATA detection which fails at line 194 sata_port_map...in lynxpoint.go by removing most SATA related *.go code.

After that autoport will progress but hang on USB not being correctly detected so I also hacked USB out of *.go files leaving me with half a build which doesn't build... The elephant in the room for this board support is probably adding coreboot memory init support for the soldered RAM config but first things first?

Digging further it seems that inteltool misses crucial regions, which may be the reason the PCIe and USB devices are unsupported detected?

With the added logs it is possible to test/build autoport on a other machine using:
