[U-Boot-Users] Interface between u-boot and linux image

Hi,

Is there a standard of the interface between u-boot and linux image? Since the u-boot should passing some information to kernel at the begining of linux image start up, but for different CPU type, the bdinfo structures are very different in u-boot, how does these structures co-work with linux image made from different version of embedded linux such as eldk, hardhat or others? thanks.
