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.
