[coreboot] Dell R610 Support

[Ed Hau]

Hello,

I just started looking into adding support for the dell r610. This is 
mostly because you can get them really cheap and they perform well for 
my type of workloads. However looking at the wiki it looks like I have 
my work cut out for me if I am able to do this at all. From the 
following dump it looks like I have a currently unsupported chipset, 
cpu, and superIO.

# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 2.6 present.

Handle 0x0200, DMI type 2, 9 bytes
Base Board Information
         Manufacturer: Dell Inc.
         Product Name: 0K399H
         Version: A03
         Serial Number: ..CN697029680164.
         Asset Tag: Not Specified

$ root at plex-8316f3de71:~# superiotool -d
superiotool r6637
Found SMSC EMC2700LPC (id=0x67, rev=0x01) at 0x2e
No dump available for this Super I/O

$ root at plex-8316f3de71:~# inteltool
CPU: ID 0x106a5, Processor Type 0x0, Family 0x6, Model 0x1a, Stepping 
0x5
Northbridge: 8086:3403 (unknown)
Southbridge: 8086:2918 (ICH9)


It looks like I will have to contact SMSC which was acquired by 
microchip in 2012 so hopefully they are still able to give me the 
datasheet. Additionally I will need to get the datasheet from intel for 
CPU north/south bridge which from the docs sounds like it might take a 
while if they will even give it to me at all.

Does this seem like a good place to start? I wasn't able to find much 
outside of https://www.coreboot.org/Developer_Manual so figured I would 
ask for a little bit of help getting started on the mailing list first.

Thanks for looking
