Because an opteron CPU has three hypertransport links. Each device reflects one of the links.
BUT: This is an overspecification in the device tree and it will likely fail, print errors or otherwise do the wrong thing if you only put 2 CPUs on that board. The selection of the driver in Kconfig should be enough for coreboot to do the right thing. Is it not?

Hi,
I read in earlier mailing list entries that it is not necessary to put all 4 cpu in the device tree since coreboot detects them automatically. So I only go with 18 because it got the MCP 55 and 19 because thats where the amd 8132 is. If you thing it is better to put all 4 cpu in the device tree to avoid trouble I will do that.
