[coreboot] Where to find document for bayou.xml?

[jasonzhao]

hi Jordan,
Do you have any document talking about how to write a BAYOU xml file,where to get it?
Or, can you tell me where is wrong in the bayou.xml at below?
Many thanks.

I have a bios.bin.elf(seabios binary file) and coreinfo.elf included in my bayou.elf, so a bayou.xml is written based on bayou.xml.example, but BAYOU fails to parse it at run time:
The serial output has some messy code, and the screen output only have "default chain" and "y"(keyboard can be used to choose, but pressing [return] has no response). 

Here are the details info:
